Motor neurone disease (ALS) destroys motor neurones controlling movement. About 5–10% of cases are familial with C9orf72 expansions being the most common cause.
How Genetic Is Motor Neurone Disease?
Genetics plays a meaningful role in Motor Neurone Disease, with heritability estimated at around 61%. However, environmental factors — including diet, lifestyle, and exposure — also significantly influence risk.
Key genes associated with Motor Neurone Disease: SOD1,C9orf72,TARDBP,FUS. Variants in these genes have been identified through genome-wide association studies (GWAS) and clinical research as influencing susceptibility or severity.
