rs13181, also known as c.2251A>C, p.Lys751Gln and K751Q, is a variant in the ERCC2 gene on chromosome 19. A meta-analysis of 20 studies, comprising 2,308 cases, ultimately concluded that the rs13181(G) allele is associated with increased cutaneous melanoma risk (odds ratio 1.12, CI: 1.03-1.21, p = 0.01; population attributable risk = 9.6%). A preliminary (as yet unreplicated) study of 430 patients with ovarian cancer concluded that rs13181(C;C) is associated with an increased risk of ovarian cancer (OR 5.01 relative to rs13181(A;A), CI: 3.37-7.43; p < 0.0001). Interestingly, heterozygotes were reported to have a lower odds ratio for developing ovarian cancer (of 0.43; CI: 0.27–0.62, p < 0.0001) compared to rs13181(A;A) individuals.
