Parkinson disease most often develops after age 50. End-stage Parkinson’s disease dementia. For the stratification of PD patients and the development of advanced clinical trials, including causative treatments, a better understanding of the underlying genetic architecture of PD is required. Monogenic forms, caused by a single mutation in a dominantly or recessively inherited. Parkinson's disease represents a fast-growing neurodegenerative condition; the rising prevalence worldwide resembles the many characteristics typically observed during a pandemic, except for an infectious cause. But while a tremor may be the most well-known sign of Parkinson's disease, the disorder also commonly causes stiffness or slowing of movement. The discovery of genetic mutations in patients with parkinsonism may offer us new insights into the understanding of the pathways leading to neuronal death and development of Parkinson's disease. If sleep is affected, people may also feel tired and drowsy during the day. Despite substantial efforts, genome-wide association studies have not. Patients with Parkinson's disease (PD) have consistently demonstrated brain structure abnormalities, indicating the presence of shared etiological and pathological processes between PD and brain structures; however, the genetic relationship remains poorly understood. doi: 10. The pathophysiology of PD is related to the accretion of synuclein alpha. Symptoms begin gradually, often on one. BOSTON – In a study published in Nature. About 15% of people with Parkinson’s have a family history of the disease. Outlook. Parkinson’s disease (PD) is an increasingly prevalent and progressively disabling neurodegenerative disease that encompasses a range of clinical, epidemiological, and genetic subtypes ( 1 ). These genes include alpha-synuc. muffled. Sleep and night-time problems are common in Parkinson's. About 15% of patients with Parkinson disease (PD) have family history and 5-10% have a monogenic form of the disease with Mendelian inheritance. Evidently many pathways have been implicated in PD, illustrating the. In most cases, no primary genetic cause can be found. They discovered that mutations in parkin result in a breakdown of contacts between two key workers. Methods We evaluated the association between 31 risk variants and variables measuring disease progression. rigid muscles, leading to. Parkinson's disease (PD) is a complex neurodegenerative disorder with a strong genetic component. Parkinson's disease; genetics; PD, Parkinson's disease; MZ, monozygotic; DZ, dizygotic; The possibility of a genetic contribution to the risk of Parkinson's disease (PD) was first described by Gowers, 1 who found 15% of his patients had a family history of the disease. While the connection appears in a small minority of people with Parkinson’s disease, scientists have found that certain genetic variants may play a role in the risk of developing the condition. S. Advertisement. Our helpline and Parkinson's advisers are here to answer any questions you have around diagnosis and your next steps. If you need emotional support urgently, the Samaritans can offer listening support 24 hours a day everyday. and 10 million worldwide. “Up until 1997, people did not broadly think that Parkinson’s could be hereditary or. Parkinson’s disease (PD) is a neurodegenerative disorder primarily characterized by motor dysfunction. The discovery of gene variants which confer risk for Parkinson's disease. In some cases, Parkinson's is caused by mutations that can be passed from parents to their biological children — but, for most people with Parkinson's, there is no family history or clear genetic cause. Here are some facts to shed some light on the issue: Only 15% of people with Parkinsons reported having someone in the family with the condition. limb stiffness or slow movement. This means it gets worse over time. Most people diagnosed with PD are age 60 years or older, however, an estimated 5 to 10 percent of people with PD are diagnosed before the age of 50. Parkinson disease is a complex, age-related, neurodegenerative disease associated with dopamine deficiency and both motor and nonmotor deficits. In this review, we focus on three. In the long term, identifying the causes of Parkinson’s disease is a crucial challenge to prevent the disease from progressing to near total neuronal loss and untreatable dysfunctions. impaired posture. In other words, Parkinson’s is a lifelong condition that affects the brain and symptoms will get worse over time. slow movements. The person may have the hallmark symptoms of tremor. However, while having a specific combination of genetics may increase your risk of the disease, it doesn’t necessarily mean that you’ll get it. We previously mapped a locus for a rare familial form of PD to chromosome 1p36 (PARK6). Within your body, nerves transmit information to and from the brain or spinal cord, which affects muscles and organs. Ali was a longtime friend of the Parkinson's Foundation. Some families experience mutations in genes inherited and passed on from one generation to another. Five main genes that are believed to contribute to the disease have been identified and located. The gut microbiome comprises all the. The inherited, or familial, type is associated. Approximately 90,000 Americans are diagnosed each year, and the general. Advertisement. Each of these conditions has its own set of symptoms, stages, and treatments. About 15% of people with Parkinson's have a family history of the. Genetic testing for Parkinson’s emerged in the 2000s after the identification of the first known disease-causing variants. The disease of Lewy Body Dementia affects cognitive response, changes physical and sleep pattern along with changing behavioral features. So far, highly-penetrant rare genetic alterations in SNCA, LRRK2, VPS35, PRKN, PINK1, DJ-1 and GBA have been linked with typical familial PD and common genetic variability at 90. Increasing evidence supports an extensive and complex genetic contribution to PD. Genetics is another concern, so people who have a family member with Parkinson's disease are at an increased risk. The underlying pathology of PD is. npj Parkinson's Disease - Author Correction: Local genetic correlations exist among neurodegenerative and neuropsychiatric diseases. Aging is the greatest risk factor for developing PD. For a relatively small number of people with Parkinson’s, genetics can play a defining role in their risk of developing Parkinson’s – for others, essentially no role at all. , dystonia and levodopa. Mayo Clinic in Rochester, Minnesota, Mayo Clinic in Phoenix/Scottsdale, Arizona, and Mayo Clinic in Jacksonville, Florida, are ranked among the Best Hospitals for neurology and neurosurgery in the U. et al. "A number of genetic factors have been shown to increase a person's risk of developing Parkinson's disease, although exactly how these make some people more susceptible to the condition is unclear. A substantial proportion of risk for Parkinson disease (PD) is driven by genetics. Mutations in alpha-synuclein have also been found to trigger Parkinson’s, but these are quite rare. Parkinson's disease (PD) is a common neurodegenerative disorder affecting patients in large numbers throughout the world. This study provides evidence that alleles associated with Parkinson disease risk, in particular GBA variants, also contribute to the heterogeneity of multiple motor and nonmotor aspects. problems with balance and tendency to fall. About 5-10% of all patients suffer from a monogenic form of Parkinson's disease. People participate in clinical trials for many reasons. Within your body, nerves transmit information to and from the brain or spinal cord, which affects muscles and organs. Two genes that are often found to contribute are the SNCA gene and the LRRK2 gene. Parkinson’s disease is a chronic and progressive brain and movement disorder that occurs in five stages. Parkinson's disease age at onset genome-wide association study: Defining heritability, genetic loci, and α-synuclein mechanisms. Parkinsons disease dementia :. Mutations in certain genes are found to cause monogenic forms of the disorder, with autosomal dominant or autosomal recessive inheritance. Though other factors are involved, there’s a significant genetic component to Parkinson’s disease. Get moving. rigid muscles. Genetic atypical Parkinson's disease (PD) describes monogenic forms of PD that resemble idiopathic PD but feature prominent atypical clinical signs and symptoms and can be sub-grouped into i) atypical monogenic forms caused by mutations in the ATP13A2, DNAJC6, FBXO7, SYNJ1, VPS13C, and DCTN genes; ii) monogenic PD more closely. Genetic testing has recently become available for the parkin and PINK1 genes. Sleep and night-time problems are common in Parkinson's. Neuronal loss in the substantia nigra, which causes striatal dopamine deficiency, and intracellular inclusions containing aggregates of α-synuclein are the neuropathological hallmarks of Parkinson disease. , Ph. Genetic markers for Parkinson's disease can run in families, but it's rare to inherit. 6 The function of alpha-synuclein is still unknown. That genetic predisposition to Parkinson's is rare, accounting for less than 2% of Parkinson's disease cases. These are important to consider and control for when evaluating GBA-PD cohorts to avoid erroneous causal. Ethnic background influences a person’s risk of developing Parkinson’s, and it. If a young person does have Parkinson's disease, genetic counseling might be helpful in making family planning decisions. Genetics of Parkinson's disease. Parkinson's disease is due to the loss of brain cells that produce dopamine. Parkinson’s disease hereditary patterns may vary depending on the altered gene. 2005 Jan;20 (1):1-10. In others, the cause is unclear, but environmental factors , such as chemicals, toxins, and head trauma, may. Researchers are also examining how genetic variation may make some people more prone to the disease, and how certain. To date, at least 23 loci and. Understanding these changes in genes is the basis for the Parkinson's Foundation PD GENEration: Mapping the Future of Parkinson's Disease study, which aims to. In these cases, the disease is caused by any of several genetic mutations passed down from one or both parents. Parkinson’s disease (PD) is a neurodegenerative disorder caused by a complex interplay of genetic and environmental factors. the genetics of Parkinson’s disease in other populations. Parkinson's disease is a chronic condition that affects the central nervous system, leading to symptoms such as difficulty walking, tremors, cognitive challenges, and, eventually, dementia. About 15 percent of people with Parkinson’s disease have a family history of the condition, and family-linked cases can result from genetic mutations in a group of genes — LRRK2, PARK2, PARK7, PINK1 or the SNCA. Genome-Wide Association Studies (GWAS) have elucidated the genetic components of Parkinson's Disease (PD). A person will need constant care and may be bound to a wheelchair and in a lot of cases, non-motor symptoms “can also appear in the form of depression, anxiety. Family studies conducted in Caucasian populations suggest Parkinson’s disease (PD) has a strong genetic component, 1 – 5 yet genome-wide association studies (GWAS) have not uncovered any new genes that reached the statistically acceptable significance level. Pathological hallmarks include neuroinflammation, degeneration of dopaminergic neurons in the. Research is also underway to find better treatments to improve life for people. Parkinson's disease (PD) is a common neurodegenerative disorder characterized by degeneration of the substantia nigra pars compacta and by accumulation of α-synuclein in Lewy bodies. In addition, research has discovered changes in about 80 genetic locations that appear to influence the risk of getting. Dystonia is one of the most common movement disorders after Parkinson’s disease (PD) and essential tremor [1,2]. ”. Having a parent with Parkinsons disease only increases your risk of getting Parkinsons by 3%. Description. studies on these families provided interesting insight on the genetics and the pathogenesis of the disease allowing the. Mutations of several genes, including synuclein alpha (SNCA) and leucine-rich repeat kinase 2 (LRRK2. The four key symptoms that doctors usually look for during diagnosis are: tremors muscle stiffness or rigidity slow movement, or bradykinesia changes in posture and balance that can increase the risk of falls A change in the LRRK2 gene known as G2019S is probably the most common genetic change linked to Parkinson’s. Many researchers think that Parkinson’s disease may be caused by genetic factors combined with other external factors. The condition is described as early-onset disease if signs and symptoms begin before age 50. These include: depression and anxiety. However, strategies aimed at ameliorating. Provide an evaluation strategy to identify the genetic cause of Parkinson. Though without a cure, treatments are available to slow it. Parkinson’s disease (PD) is a complex age-related neurodegenerative disease associated with dopamine deficiency and both motor and nonmotor deficits. The main signs and symptoms are problems with muscle coordination (ataxia), but others may include: Impaired movement and coordination, such as unsteady gait and loss of balance. People with a disease may participate to receive the newest possible treatment and additional care from clinical study staff as well as to help others living with the same or similar disease. Mitochondrial dysfunction is strongly implicated in the etiology of idiopathic and genetic Parkinson’s disease (PD). In most cases, no primary genetic cause can be found. stiff and inflexible muscles. According to the Parkinson’s Foundation, about 90% of people with the disease have no genetic link. We have tried to consolidate the contribution of Indian studies in PD research. Google Scholar Ramirez, A. This positive association. Parkinson's disease (PD) is a common neurodegenerative disorder of adulthood characterized clinically by rigidity, bradykinesia, resting tremor, and postural instability. Various types of hereditary neuropathies exist, including the following:. The field of Parkinson’s research is ongoing and ever evolving as we learn more about this disease. A sample of 122 patients with Parkinson's Disease was studied for the purpose of investigating if the frequency of relatives affected with Parkinson in this group was higher than in a control group and to see if the genetic load was more important in some of the subtypes of Parkinson described by Barbeau and Pourcher (1982). Abstract. A DaTscan involves an. The Parkinson's panel is ideal for patients with a clinical suspicion of Parkinson disease. Hereditary factors have recently emerged as a major focus of Parkinson's disease research. PINK1 type of young-onset Parkinson disease is characterized by early onset (mean age 33 years) of tremor, bradykinesia, and rigidity that are often indistinguishable from other causes of Parkinson disease. Stage five: This is the most advanced and debilitating of the Parkinson’s disease stages where “stiffness in the legs make it very difficult or impossible to walk”. Most scientists agree that the cause includes a combination of genetics and the environment. Parkinson’s disease is a neurodegenerative disorder that currently affects nearly one million people in the United States, although some estimates are much higher. Introduction Following Alzheimer’s disease, Parkinson's disease (PD) is the second-most common neurodegenerative disorder in the United States. Tremor of the hands, arms, legs, or face. And while there are some genetic markers, they don’t guarantee that a person will get the disease. Image Credit: Chinnapong/Shutterstock. July 26, 2023. We have reviewed the current literature about the genetic factors that could be indicative of pathophysiological pathways of PD and their applications in everyday clinical practice. A number of genetic factors have been shown to increase a person's risk of developing Parkinson's disease, although exactly how these make some people more susceptible to the condition is unclear. Sporadic Parkinson’s Disease (sPD) is a progressive neurodegenerative disorder caused by multiple genetic and environmental factors. In families where multiple members have Parkinson’s disease, the risk may be as great as 50% to the children of an affected person. Most cases arise spontaneously; some are hereditary. “About 10 to 20 percent of Parkinson’s disease cases are linked to a genetic cause,” says Ted Dawson, M. This is often termed as Parkinson’s disease dementia. NEW YORK & MIAMI (July 16, 2019) — The Parkinson’s Foundation is pleased to announce the launch of PD GENEration: Mapping the Future of Parkinson’s Disease, a first-of-its-kind national initiative that offers free genetic testing for clinically relevant Parkinson’s-related genes and free genetic counseling to help participants better. slowing of thoughts. In one large family in Salerno, Italy, 50 of 592 members had Parkinson disease; linkage analysis incriminated a region in bands 4q21-23, and sequencing revealed an A-for-G substitution at base 209 of the alpha-synuclein. Researchers have found several genes. At the current stage of understanding, testing is likely to give a meaningful result only for people who develop the condition before the age of 30 years. Those who carry this gene may be more likely to experience early symptoms such as bradykinesia (slowness of movement) and rigidity. Genetic testing is resulting in more precise, effective trials and treatment since new therapies are regularly being developed for certain. Parkinson’s affects about one million people in the U. et al. Other risk factors include:Genetic testing is not part of the routine evaluation of individuals with Parkinson disease (PD) and is rarely offered in late-onset PD. Introduction. It can be a symptom of many different neurological conditions, such as Alzheimer’s disease. trouble walking. The symptoms usually emerge slowly, and as the disease worsens, non-motor symptoms become more common. However, in public awareness. Parkinson's disease, a disorder of unknown cause, is a distinct clinical and neuropathologic entity, characterized clinically by bradykinesia, resting tremor, cogwheel rigidity, and postural reflex impairment. Other associated features are a loss of smell, sleep dysfunction, mood disorders, excess salivation, constipation, and excessive periodic limb. Description Parkinson's disease is a progressive disorder of the nervous system. Experts have identified several genes in which changes may result in Parkinson’s disease, but these are not necessarily hereditary. The disease is common with a prevalence ofbetween 500 000–1 000 000 in the United States ( 2 ). A juvenile form of Parkinson disease is also recognized, manifesting between 20-40 years of age 1. 12X. Parkinson's Genetics. Parkinson’s disease is a progressive neurological disorder that affects motor function, causing tremors, bradykinesia, and rigidity. “Although Alzheimer’s and Parkinson’s disease are molecularly and clinically very different disorders, our results support the idea that the problems that cause those diseases may also. Parkinson’s disease (PD) is a heterogeneous age-associated incurable neurodegenerative syndrome, occurring in both sporadic and familial forms. Parkinson's disease (PD) is a common neurodegenerative disorder that usually affects the elderly. Given that these mutations can be passed from parents to their biological children, they are associated with Parkinson’s that runs. Parkinson’s disease (PD) is the second most prevalent neurodegenerative condition, affecting 1 in 100 people over the age of 60 1 and an estimated 6. The symptoms usually emerge slowly, and as the disease worsens, non-motor symptoms become more common. Heredity. A genetic disease can be hereditary, but not always. Parkin type of early-onset Parkinson disease (PARK-Parkin) is characterized by the cardinal signs of Parkinson disease (PD): bradykinesia, resting tremor, and rigidity. 1 million in 2016. People with vascular parkinsons have similar symptoms to Parkinson's disease, but may also have other symptoms such as problems with memory, sleep and mood. The main symptoms of Parkinson's disease affect physical movement: tremor – shaking, which usually begins in the hand or arm and is more likely to occur when the limb is relaxed and resting. Exercise your brain. About 5-10% of all patients suffer from a monogenic form of PD where mutations in autosomal-dominant (AD) genes-SNCA, LRRK2, and. ;Children of parents with Huntingtons;have a 1 in 2 chance of developing it as well. Learn more about the genes that are connected to PD and the role. Nucleotides with >1000x MQ0 sequencing coverage (%) (clinical) 100%. The loss of dopaminergic neurons in the substantia nigra and Lewy bodies in remaining neurons are pathologic. People with Parkinson’s are more likely to experience insomnia due to certain symptoms which can disrupt sleep. A subreddit about Parkinson's Disease. Only 10 to 15 percent of total cases of Parkinson’s is hereditary. Parkinson’s happens when cells in the brain that produce dopamine stop working or die. In such cases, it is often due. In Parkinson's disease, at least some genetic risk is likely intrinsic to a neuronal subpopulation of cells in the brain regions affected. Dementia is the general term for symptoms affecting a person’s memory, thinking, and communication. Goal 2. 20316. J Neurol 2001; 248: 833–840. Aside from direct genotype–phenotype correlations within GBA-PD, several other genetic and environmental factors may influence both disease penetrance and clinical features. Over recent years, many variants in a growing number of genes involved in the pathogenesis of Parkinson's disease have been identified. Before. Early signs and symptoms of Parkinson's disease include tremors or trembling, slow movement, body rigidity and stiffness, and problems walking. Introduction Parkinson’s disease (PD) is a neurodegenerative condition affecting over 6 million people worldwide that is expected to double in prevalence by. Parkinson's disease represents a fast-growing neurodegenerative condition; the rising. This technique allows doctors to see detailed pictures of the brain’s dopamine system. PD is caused by a combination of environmental factors and genetic variants. For most people with Parkinson’s disease, there is no inherited link. Aging is the greatest risk factor for developing PD. . Parkinson’s disease is the second most common neurodegenerative disorder, after Alzheimer’s disease. Parkinson disease is a neurodegenerative disorder that mostly presents in later life with generalized slowing of movements (bradykinesia) and at least one other symptom of resting tremor or rigidity. Recent findings: Mutations in autosomal dominant genes (e. Genetic testing for Parkinson’s disease. 2017). Some familial forms of Parkinson's disease, in fact, are due to genetic mutations (LRRK2, Leucine-rich repeat kinase) 21. But research points to a combination of genetic and environmental factors as likely causes. People who carry this gene change may develop Parkinson's later in life. Family history plays a role in a small percentage of cases, but environmental factors and age also heighten the risk. Around 15% of people living with Parkinson’s have a family history of the condition, either an immediate or second-degree. Key Points. 70 , 1268. These cells control the production of the chemical dopamine. Vascular parkinsonism. Commun. 5 million in 1990 to approximately 6. Abstract. Hereditary parkinsonism with dementia.

In this article, we review all the published data on PD based on studies in Indian population. January 23, 2018. If you inherit a Parkinson’s disease gene, you have a higher chance of. These include tremor, stiffness, pain and restless leg syndrome. WPW syndrome may occur with other types of congenital heart disease, such as Ebstein anomaly. Population prevalence of PD increases from about 1% at age 60 to 4% by age 80. Parkinson disease is a movement disorder. Although our. However, 10-15% of patients have a positive family history 1. Parkinson’s disease is the fastest-growing neurological disorder worldwide. Mitochondrial dysfunction represents a well-established player in the pathogenesis of both monogenic and idiopathic Parkinson’s disease (PD). While this condition is best known for how it affects muscle control, balance and movement, it can also cause a wide range of other effects on your senses, thinking ability, mental health and more. Nope, Parkinson’s isn’t considered a hereditary disease in most people. It generally onsets between the ages of 55 to 65 and rarely occurs before the age of 50. Advances in genetic sequencing, for instance, have revealed that up to 15 percent of all cases of Parkinson’s can be attributed to inherited mutations in a person’s DNA. This panel includes assessment of non-coding variants. So far, highly-penetrant rare genetic alterations in SNCA, LRRK2, VPS35, PRKN, PINK1, DJ-1 and GBA have been linked with typical familial PD and common genetic variability at 90. Parkinson’s disease.

When there are multiple family members with Parkinson’s disease, we refer patients for genetic counseling. Some rare types of Parkinson’s disease cases are hereditary (passed from parents to child). The scientists contrasted the incidence and age of onset of Alzheimer’s and Parkinson’s among people with DR4 versus those without it and found a roughly 10% risk reduction in those carrying DR4. They may also have mental and behavioral changes. Depending on the stage, a person with Parkinson’s may experience problems with. Mayo Clinic doctors are experienced, evaluating and treating about 4,900 people with Parkinson's disease each year. Estimates vary, but somewhere between 5 and 10. As nerve cells (neurons) in parts of the brain weaken, are damaged, or die, people may begin to notice problems with movement, tremor, stiffness in the limbs or the trunk of the body, or impaired balance. All cells have coded instructions in their genes. has been placed on other inherited conditions that may also present with signs of parkinsonism or even mimic idiopathic Parkinson's disease clinically. Healthy volunteers may participate to help others and to contribute to moving science forward. Resolving.

In the UK, around 1 in 100 people with Parkinson’s carry it. At a time when Parkinson’s disease was mostly viewed as a textbook example of an environmentally caused disease, the idea of Parkinson’s being genetic in origin was simply revolutionary. Parkinson’s disease dementia is a decline in thinking and reasoning skills that develops in some people living with Parkinson’s at least a year after diagnosis. Study: An optimized Nurr1 agonist provides disease-modifying effects in Parkinson’s disease models. Parkinson's disease is neurodegenerative, the second most common disorder of this type after Alzheimer's disease. Some people with the vascular condition experience a resting tremor, but this usually occurs later in the course of disease. Most cases of Parkinson’s happen in people with no family history of the disease. Although the disease remains defined clinically by its cardinal motor manifestations and pathologically by midbrain dopaminergic c. That’s where the Parkinson’s Foundation’s PD GENEration study, a national initiative to test and map the genes most relevant to PD, steps in. In these cases, the disease is caused by any of several genetic mutations passed down from one or both parents. Parkinson's 360: Michael Fitts' journey with PD Causes. He was diagnosed with Parkinson's just three years after retiring from boxing. Dopamine helps control. Parkinson's disease can be caused by rare familial genetic mutations, but in most cases it is likely to result from an interaction between multiple genetic and environmental risk factors. While this condition is best known for how it affects muscle control, balance and movement, it can also cause a wide range of other effects on your senses, thinking ability, mental health and more. “Our results suggest the importance of.

Additionally, people with PD can also experience other physical and non-movement symptoms, such as: Depression and anxiety. If you feel comfortable walking, swimming, or riding an exercise bike. Introduction. Parkinson's disease (PD) is a neurodegenerative disorder characterized by degeneration of dopaminergic neurons in the substantia nigra. Learn about its various symptoms, how it is diagnosed, treated, and most importantly, how to live a better life with Parkinson's. Genetic causes. The types are either autosomal dominant or autosomal recessive . There are five stages of Parkinson's disease. People with Parkinson’s are more likely to experience insomnia due to certain symptoms which can disrupt sleep. Genetic testing for Parkinson’s disease (PD) is increasing globally, and genetic counseling is an important service that provides information and promotes understanding about PD genetics and. It develops gradually, sometimes starting with a barely noticeable tremor in just one hand. It may be that as many as two-thirds of people with Parkinson's are male. In 2017, Sanofi Genzyme launched a phase 2 clinical trial of a drug designed to target a specific genetic mutation in some patients with Parkinson's disease (PD). Read about Non. In people with young onset Parkinson’s disease (YOPD), onset of symptoms is between 21 and 40 years of age. GettyIn almost 70 years, our understanding of how Parkinson’s disease wreaks havoc on the nervous system has grown tremendously. It is clinically defined by the presence of bradykinesia in combination with either rest tremor and/or rigidity, and a clear beneficial response to dopaminergic therapy []. These include tremor, stiffness, pain and restless leg syndrome. But if you have a parent with Parkinsons disease, you have about a fourfold greater risk over the general.
