Rs4430796

rs4430796 is a SNP in the TCF2 gene on chromosome 17q12, associated with increased risk for prostate cancer in several studies.

In a study of over 3,600 Caucasians with prostate cancer, rs4430796 is one of five SNPs used (with family history as a sixth factor) to cumulatively predict overall risk. On its own, the rs4430796(A;A) risk genotype - in dbSNP orientation, not as published - yields an odds ratio for developing prostate cancer of 1.38 (CI: 1.21-1.57, p=1.6x10e-6) and may account for 10.2% of population attributable risk.

403 non-Hispanic white families were studied, totaling 1,015 men, to reach the conclusion that the rs4430796(A) allele is associated with increased prostate cancer risk; the odds ratio was 1.40 (CI: 1.09-1.81) under an additive genetic model. Notably, rs4430796(A) was significantly associated with prostate cancer among men diagnosed at an early (<50 years) but not later age (P = 0.006 versus P = 0.118). The increased risk associated with rs4430796 and the closely linked rs7501939 is approximately doubled in individuals hereditarily predisposed to develop early-onset prostate cancer.
