Single Nucleotide Polymorphisms in Human Gene icb-1 and Breast Cancer Susceptibility

Abstract

In this study, we tested the hypothesis that single nucleotide polymorphisms (SNPs) of differentiation-associated human gene icb-1 (C1orf38) may be associated with breast cancer susceptibility. A total of 646 women—323 breast cancer cases and just as many controls—were included. Breast cancer patients more frequently carried the homozygous genotype AA of SNP rs1467465 than did healthy women. Analysis of allele positivity revealed that AG or GG genotypes were significantly less frequent in breast cancer patients, suggesting that presence of G allele might have protective effects. Our data suggest that SNP rs1467465 of human gene icb-1 might affect breast cancer susceptibility.
