Rs1136410

rs1136410, also known as V762A, is a SNP in the PARP1 Poly(ADP-ribose) polymerase-1 gene. The rs1136410(C) allele encodes the less common A (alanine) amino acid at this codon.

A study of 1,000 glioblastoma multiforme cases and 2,000 controls in the US concluded that the PARP1 gene rs1136410(C) allele was associated with a 20% reduction in risk for glioblastoma multiforme (odds ratio 0.80, CI: 0.67-0.95).

A meta-analysis of 21 studies with 12,027 cancer patients found no significant association overall between rs1136410 and cancer risk, however, in the stratified analyses, rs1136410(C) was associated with an increased risk of cancer among Asian populations (CT + CC vs. TT: odds ratio 1.11, CI: 1.01-1.23, p(heterogeneity) = 0.210), but a decreased risk of cancer (CT + CC vs. TT: odds ratio 0.89, CI: 0.80-1.00, p(heterogeneity) = 0.004) among Caucasian populations, especially for glioma risk (odds ratio 0.79, CI: 0.69-0.90, p(heterogeneity) = 0.800).
