Article Title: | Genetic variation in SIPA1 in relation to breast cancer risk and survival after breast cancer diagnosis |
Abstract: | Genetic variation in SIPA1, signal-induced proliferation-associated gene 1, has been proposed to be associated with aggressive breast tumor characteristics related to metastasis and worse prognosis in humans and rodents. To test this hypothesis, we genotyped 3 single nucleotide polymorphisms (SNP) located at -3092 (A<G, rs931127), exon 3-135 (C>T, rs3741378), and exon 14 1 14 (C>T, rs746429), and examined them in relation to breast cancer risk and overall survival, stratified by tumor characteristics in 2 independent case-control studies conducted in Poland (1,995 cases, 2,296 controls) and in Britain (2,142 cases, 2,257 controls). Vital status (n = 396 deaths) was available for 911 Polish and 1,919 British breast cancer cases with an average follow-up time of 5.5 years. Overall, we found no significant associations between genetic variants of SIPA1 SNPs and breast cancer risk (per allele odds ratios, 95% confidence intervals (CI): rs931127-0.99, 0.931.06; rs3741378-1.03, 0.94-1.13; and, rs74642-0.98, 0.92-1.04). In both studies, SIPA1 polymorphisms were not related to overall mortality (per allele hazard ratios, 95% CI: 1.02, 0.88-1.17; 0.90, 0.72-1.11; 1.04, 0.90-1.21, respectively). Our results do not support a relationship between SIPA1 polymorphisms and breast cancer risk or subsequent survival. © 2008 Wiley-Liss, Inc. |
