Huntington disease (HD)

Huntington disease (HD) is caused by a CAG trinucleotide repeat expansion in 3-5 out of 100,000 individuals. The test is diagnostic and Labcorp requires an informed consent. Genetic counseling services are available.

Amyotrophic Lateral Sclerosis (ALS)

ALS, often referred to as Lou Gehrig’s disease, is among the most devastating neurodegenerative diseases. Though its causes are mostly unknown, this adult onset disease can have a genetic etiology 10% of the time. Labcorp offers genetic testing that may help identify ALS, including:

C9orf72 Genetic Testing

Around 30% to 40% of familial ALS in the US can be attributed to variations in the C9orf72 gene.

SCA2(ATXN2) Genetic Testing

It has recently been found that repeat expansions within the ATXN2 gene can cause ALS in 5% of patients.

Finding a way to diagnose Alzheimer's earlier and easier is a key goal for Labcorp.

Muscular Dystrophy

Characterized by progressive muscle loss and weakness, our tests can detect the genetic mutations that cause the most common forms.

Multiple Sclerosis

While no single test can diagnose multiple sclerosis, lab tests may help doctors rule out other diseases and confirm a diagnosis.

Biomarkers for Drug Development

The increasing prevalence of neurodegenerative diseases has fueled the need for advanced research into pharmaceutical solutions and related neuro biomarkers.
