Genetic Testing And Genetic Counselors
Genetic counselors are healthcare professionals who help interpret genetic test results and explain the implications of the results for the individual tested, as well as for family members. The PD GENEration study uniquely offers genetic counseling in both English and Spanish to all people with PD.
Genetic testing helps estimate the risk of developing Parkinson’s, but is not a diagnosis and cannot provide a timeline for the possibility of developing a disease. With any genetic test results, it is important to discuss your results with a licensed genetic counselor.
Free Genetic Testing Through Als Identified
The ALS Association believes that upon diagnosis, people living with ALS/MND and their families must have the right to access genetic counseling and testing, current education about clinical genetics in ALS/MND and safeguards against genetic discrimination.
The ALS Identified program, sponsored by Biogen and offered through the diagnostic company Invitae, offers genetic testing to people with ALS and their families at no charge.
Invitaes ALS Panel looks for mutations in more than 20 genes that are associated with ALS, including the C9ORF72 gene. It’s available to people with ALS and people with a family history of ALS in the U.S. and Puerto Rico. Only a doctor can order this test for you.
You may take this test at home or in a doctors office. If you take it at home, you’ll receive a testing kit in the mail and you’ll mail back a cheek swab in a prepaid envelope. If you take the test a doctors office, you’ll supply either a blood, saliva, or cheek swab sample.
About 2-3 weeks later, your doctor will receive your results. Your doctor and/or genetic counselor will have access to the results, who will share them with you and take time to explain the results and their impact on you and your family.

Genetic Testing Is Primarily For Research Not Care
Genetic testing as part of a research study is not necessarily intended to provide you with personal medical information and, in some studies, you may not learn your results. As of this writing, even if you discover that you do carry a genetic mutation, these results will not significantly alter your personal medical care. Some studies are testing new therapies in mutation carriers. Your genetic status may allow you to participate in research studies, partnering with scientists to add to our existing knowledge about brain disease and help evaluate new treatments.

Cost Of Predictive Genetic Testing For Huntingtons Disease At Centers Of Excellence In The Us
M. Massey, T. Orem, V. Sung
Objective: To characterize the cost of Huntingtons disease predictive genetic testing at Centers of Excellence in the US.
Background: Despite the availability of predictive genetic testing for the diagnosis of Huntingtons disease , most at-risk individuals choose not to undergo testing. Cost of the predictive testing process may play a role in this, but data on this cost are limited. Huntingtons Disease Society of America certifies Centers of Excellence in the US, and many patients pursuing predictive testing for HD seek to do so at these COEs. Here we describe the costs of this predictive testing process at COEs in the US.
Method: All HDSA-certified COEs agree to perform HD predictive genetic testing adhering to the 2015 HDSA Genetic Testing Protocol1. Existing COEs submit annual progress reports to HDSA containing detailed information about their genetic testing process, including costs of each component of the process at their site. Data from progress reports submitted in 2018 and 2019 were de-identified and summarized.

Bioinformatics And Clinical Interpretation
We provide customers with the most comprehensive clinical report available on the market. Clinical interpretation requires a fundamental understanding of clinical genetics and genetic principles. At Blueprint Genetics, our PhD molecular geneticists, medical geneticists, and clinical consultants prepare the clinical statement together by evaluating the identified variants in the context of the phenotypic information provided in the requisition form. Our goal is to provide clinically meaningful statements that are understandable for all medical professionals regardless of whether they have formal training in genetics.
Variant classification is the cornerstone of clinical interpretation and resulting patient management decisions. Our classifications follow the ACMG guideline 2015.
The final step in the analysis is orthogonal confirmation. Sequence and copy number variants classified as pathogenic, likely pathogenic, and variants of uncertain significance are confirmed using bi-directional Sanger sequencing or by orthogonal methods such as qPCR/ddPCR when they do not meet our stringent NGS quality metrics for a true positive call.

Navigating The World Of Genetic Testing
Most people think of Parkinsons disease as solely a movement disorders that starts with a hand tremor and progresses over time. In fact, Parkinsons is a disease that brings with it movement and non-movement symptoms. Specific symptoms experienced, their severity and the rate of progression along with how they respond to medication can vary significantly from person to person living with Parkinsons.
Scientists have identified more than 90 gene variants that are associated with Parkinsons. PD, if inherited, can be:
- Autosomal dominant gene variants: a dominant version of a gene that shows its specific trait even if only one parent passed the gene to the child. These PD-related gene variants include SNCA, LRRK2 and VPS35.
- Autosomal recessive gene variants: shows its specific trait when both parents pass the gene to the child. These PD-related gene variants include PRKN, PINK1 and PARK7 .
of all Parkinson’s is caused by genetics.
Variants in the GBA gene, the most common Parkinsons-related gene, are believed to be a major risk factor for PD whether inherited from one or both parents. Understanding the genetic differences across people with PD could help uncover important clues as to how and why each person’s experience with PD differs.
About the Study
Genetic test: a test that looks for one mutation in one gene at a time.
Panel test: a test that looks for mutations in multiple genes.
The Power Of Genetic Testing
Genetic testing can be a powerful tool to uncover biological pathways that cause Parkinsons disease , and this understanding can lead to improved treatments and care for all people with Parkinsons. Understanding genetic differences across people with Parkinson’s can help identify clues about how and why a persons experience with the disease differs from others. Genetic testing can also help people with PD and their clinicians identify whether they may qualify for enrollment in certain clinical trials.
Currently, genetic tests for PD are often not affordable and not covered by health insurance. Importantly, many genetic tests do not offer genetic counseling, which can help interpret test results. Therefore, most people with PD and their clinicians do not know if they carry genetic changes in important Parkinsons-related genes. Through PD GENEration, the Parkinson’s Foundation aims to address this unmet need.

How Many People Live With Parkinsons
Nearly one million Americans and 10 million people worldwide live with PD, making it the second most common neurodegenerative condition after Alzheimers.
Approximately 60,000 Americans are diagnosed with PD each year. The number of people with PD will increase substantially in the next 20 years due to the aging of the population.

Don’t Miss: Secondary Symptoms Of Parkinson’s Disease
The Decision To Seek Genetic Testing Is A Personal One
Learning you carry a gene mutation that raises disease risk can be concerning for you and your family. The decision to seek genetic testing or to participate in genetic research deserves extra attention. A genetic counselor is trained to talk with you and help you gain a fuller understanding of what your results might mean for you and your family.
Genetic Testing Cannot Tell You If You Will Or Will Not Get Parkinsons
Parkinson’s is not linked to any single gene mutation that causes disease 100 percent of the time. If you do test positive for a PD-linked mutation, it does not mean you will absolutely get Parkinson’s. There are actions you can take, such as exercise, to lower risk. Conversely, if you test negative for a PD-linked mutation, you may still develop Parkinson’s. Other mutations and factors such as aging and environmental causes also contribute to risk. Science is working to better understand who does get Parkinson’s and why.
What Genes Does Pdgeneration Test
PD GENEration: Mapping the Future of Parkinsons Disease uses the most comprehensive genetic test to detect changes in genes associated with Parkinsons disease . The test includes all genes that the medical community believes are linked to PD. For an overview of the PD GENEration testing panel, watch this informational video.
The PD GENEration test identifies variants in seven Parkinsons-related genes that include: GBA, LRRK2, PRKN, SNCA, PINK1, PARK7 and VPS35.
Can Researchers Access The Genetic Samples And Data Collected Through Pd Generation
Yes. Anonymized, confidential data from PD GENEration is open to researchers working to develop new tools, knowledge and therapy options for people with PD. Enrollment in this flagship initiative will also allow the largest, active clinical trial for PD in the world the Parkinsons Outcomes Project to link genetic status with clinical outcomes. Participants DNA and blood samples will continue to be securely stored to allow potential testing for new Parkinsons genes discovered in the future.

Is It Worth Getting A Genetic Test For Dementia Risk Variants
Genetic tests for dementia risk variants are not recommended. This is because knowing whether someone has genetic risk variants does not mean knowing for certain whether they will develop dementia. A person who has risk variants may have a higher risk of developing dementia, but even someone at a higher risk may never develop the condition.
What Are The Chances Of Getting Cancer If It Runs In Your Family
Reality: Most people diagnosed with cancer dont have a family history of the disease. Only about 5% to 10% of all cases of cancer are inherited. Myth: If cancer runs in my family, I will get it, too. Reality: Sometimes, people in the same family get cancer because they share behaviors that raise their risk.

What Can A Genetic Test Tell Me
About two-thirds of individuals with familial ALS and 10% of people with sporadic or singleton ALS have a known ALS-associated genetic mutation. If you have familial ALS, a genetic test may help you determine what’s causing your ALS, as well as the risk of disease in your family members.
Knowing whether your ALS is connected to a specific gene mutation could make you eligible for ongoing clinical drug trials that might be available for those who test positive for one of the specific genes.
In the future, it could also point you or your family members to a gene-targeted therapy . Click here to learn more about the genes involved in ALS and why genetic testing is useful.
If a test finds that you have an ALS-associated genetic mutation, your biological family members might also want to get tested, even if they don’t have symptoms. A test could help them find out if they have inherited the same ALS-associated genetic mutation.
This type of genetic testing, called predictive genetic testing, often requires individuals who don’t yet have symptoms undergo a neurological exam, psychological assessment and genetic counseling before getting tested. Learning your personal genetic status may be helpful in the future.
The decision to have predictive genetic testing is very individual and all potential benefits and costs should be discussed with a genetic counselor. Learn more about genetic counseling here.
Why Choose Pd Generation Over Other Available Tests
Not all genetic tests are created equally. PD GENEration offers the best, most comprehensive testing for genetic mutations relevant to Parkinsons disease, and is facilitated by a healthcare professional and genetic counselor through participating Centers of Excellence and Parkinson Study Group sites. Designed specifically for Parkinsons, PD GENEration tests for variants of the seven genes most connected to PD including LRRK2, GBA, and SNCA. Other currently available tests are either less specific to PD, or screen for fewer variants related to the disease.

Expanding Research And Access To Genetic Testing
Lehr said that currently, genetic tests for PD are often unaffordable and not covered by health insurance. Moreover, many entities providing genetic tests do not offer genetic counseling, which is key to interpreting test results.
Because of this, most people with PD and their clinicians do not know if they have a genetic component to their disease, he said.
The Parkinsons Foundation is working to address this unmet need through their work with PD GENEration: Mapping the Future of Parkinsons Disease, an international initiative offering no-cost genetic testing and genetic counseling for people with PD. It is one of the worlds largest genetic testing studies to identify those with genetic mutations so they can participate in upcoming clinical trials.
In the research arena, the Parkinsons Foundation funds investigator- and center-led basic research looking into the underlying causes and basic biology of PD. It also funds research on patient outcomes to see which investigations are having the greatest impact.
Lehr noted that the lack of new drugs to treat PD is due, in part, to the complexity of neurological diseases.
Progress toward new medicines, better therapies and eventually a cure relies, almost exclusively, on innovative, high-quality research, he said. If we hope to improve the lives of those living with PD today, as well as those in the future, research efforts must be intensified.
Will My Test Results Impact My Health Insurance
What about my childrens health insurance? Will my genetic testing results ever be sent to my health insurance company or employer?
Participants genetic results will never be shared with third parties such as health insurance companies or employers. Testing results will be securely sent to Centers of Excellence and/or Parkinson Study Group sites that will then confidentially communicate results to participants.

How Genetic Testing Can Help Advance Clinical Trials For Parkinsons Disease
PD GENEration aims to uncover new genetic links to Parkinsonâs disease to help advance clinical trials.
At least 10 million people worldwide have Parkinsons disease. But patients often go through long, challenging steps to arrive at a diagnosis and start treatments. Although genetic testing can improve the diagnostic process and lead to more appropriate treatments, tests are expensive, often hard to access, and are not routinely performed. In 2019, the Parkinsons Foundation launched PD GENEration: Mapping the Future of Parkinsons Disease, a comprehensive study that offers genetic testing and counselling at no cost to individuals diagnosed with Parkinsons disease, to help improve their treatment, and to find new participants for clinical trials testing targeted therapies. James Beck, Chief Scientific Officer of the Parkinsons Foundation, discusses the challenges surrounding Parkinsons disease diagnosis.

Genetic Testing For Parkinsons Disease: What You Need To Know
Parkinsons disease is the second most common neurodegenerative condition after Alzheimers, with nearly one million Americans living with the disease and ten million people affected worldwide.
With genetic testing now available, people with Parkinsons and their families are increasingly turning to testing to learn more about their disease and if their children are at risk.
Which test to take and how to interpret the results, though, can be confusing. Getting genetic testing can be useful, but the information can be overwhelming or even misleading, says neurologist Roy Alcalay, MD, an expert in the treatment of Parkinsons at Columbia and NewYork-Presbyterian who also studies the genetics of the disease.
That why its best to couple any testing with genetic counseling. Getting genetic testing is pretty profound, because people receive a lot of potentially positive or negative information. Without a genetic counselor to prepare you and explain the results, I would advise against genetic testing, says Alcalay.
What Is Genetic Testing And Why Is It Important For Parkinsons
Genetic testing, which can be performed through a blood draw or at-home sample collection, is a type of medical test that identifies changes, or variants, in genes. Some of these changes may increase the chances of developing a particular disease or predict which treatment may be more beneficial.
For people with PD, genetic testing can let you know if you carry known gene changes linked to the disease. Its estimated that 10 percent of people with PD have a genetic form of the disease, so by better understanding how those with genetic forms of PD experience symptoms related to Parkinsons and respond to treatment, scientists can begin to develop improved treatments and personalized medicines.
A deeper understanding of the genetics of PD may also lead to better treatments themselves by revealing novel therapeutic targets, spurring the development of better drugs. Genetic testing can also help people with PD and their clinicians identify whether they may qualify for enrollment in certain clinical trials.
