Notes
rs63750550, also known as c.349C>G, P117A or Pro117Ala, and also as c.349C>T, p.Pro117Ser and P117S ,is a SNP in the presenilin 1 PSEN1 gene. Inherited as an autosomal dominant, the rare rs63750550(G) and rs63750550(T) alleles are both considered pathogenic for early-onset Alzheimer's disease according to AlzForum. Reported in to be a "definitely" pathogenic mutation.
