Labcorp provides a suite of neurogenetic test options to confirm diagnosis and help patients and families with future planning.

Spinocerebellar Ataxias (SCA)

Many forms of ataxia are genetic in origin. Labcorp offers one of the most comprehensive menus to testing for various axatias.

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.
