Primary lateral sclerosis is an upper motor neurone disease. Most cases are sporadic but a small proportion have identifiable genetic causes overlapping with ALS genes.

How Genetic Is Primary Lateral Sclerosis?

Genetics plays a meaningful role in Primary Lateral Sclerosis, with heritability estimated at around 10%. However, environmental factors — including diet, lifestyle, and exposure — also significantly influence risk.

Key genes associated with Primary Lateral Sclerosis: ALS2,SPG11,UBQLN2. Variants in these genes have been identified through genome-wide association studies (GWAS) and clinical research as influencing susceptibility or severity.
