rs63750215, also known as c.422A>T, N141I or Asn141Ile, is a SNP in the presenilin 2 PSEN2 gene.
Inherited as an autosomal dominant, the rare rs63750215(T) allele is considered causative for early-onset Alzheimer's disease; see [PMID 8661049]. The actual age of onset appears to be somewhat modified by other loci.[PMID 15389756]
