Rs2228001

rs2228001, also known as Lys939Gln, K939Q, and K940Q, is a SNP in the DNA nuclear excision repair gene xeroderma pigmentosum complementation group C XPC gene. The Lys (K) allele is encoded by the rs2228001(A) allele.

A meta-analysis of 16 studies with 6797 cancer cases and 9018 controls concluded that rs2228001(C;C) homozygotes had an increased overall cancer risk (odds ratio of 1.16, CI: 1.05-1.28) compared with (A;A) homozygotes. This was primarily a risk for lung cancer.
