Abstract

Abnormalities in the breast cancer tumor suppressor genes (BRCA1 and BRCA2) are associated with breast and ovarian cancer. Recently, two single nucleotide polymorphisms (SNPs; rs11571836 and rs1799943) were identified, both located in untranslated regions of chromosome 13, associated with cardiovascular disease (CVD) in a multi-ethnic population. We examined the association between these BRCA2 polymorphisms and traits of CVD patients from Saudi Arabia. We genotyped rs11571836 and rs1799943 in 159 unrelated CVD patients and 176 healthy controls. The genotype and allele distributions in the overall population revealed a statistically significant association between rs1799943 and CVD (P = 0.01-0.022), whereas no risk association was identified for rs11571836. Additionally, haplotype analysis using both SNPs demonstrated no association between the SNPs and CVD. The genotype distribution of the 2 SNPs in the normal Saudi population deviated significantly (P
