The use of genetic testing in amyotrophic lateral sclerosis (ALS): a practical approach

Amyotrophic lateral sclerosis (ALS) is a rare and fatal neurodegenerative disease thought to be precipitated by genetic, environment and lifestyle factors. In the UK, whole genome sequencing has become available to all people living with ALS, regardless of their family history or age of onset of disease. However, there is currently no formal guidance on how to deliver genetic counseling and testing in busy mainstream clinics. This article offers practical suggestions to clinicians who may wish or need to discuss genomic testing. As more clinical trials and targeted gene therapies develop, it is likely that conversations will evolve, reflecting the dynamic nature of this important and complex field.
