}}[[rs4938369]], also known as -918G/A, is a SNP in the beta-site APP-cleaving enzyme 1 [[BACE1]] gene.

A case-control study (429 cases and 346 controls of Han Chinese descent) reported that [[rs4938369]](C;C) homozygotes had a 1.67x higher risk for sporadic [[Alzheimer's disease]] than (C;T) or (T;T) individuals (odds ratio 1.667, CI: 1.087-2.556, p = 0.019).{{PMID|19441127}}
