Fas single nucleotide polymorphisms and risk of thyroid and salivary gland carcinomas: a case-control analysis.
BACKGROUND: The purpose of this study was to examine the association between 4 Fas single nucleotide polymorphisms (SNPs) and risk of differentiated thyroid carcinoma (DTC) and salivary gland carcinoma (SGC). METHODS: We conducted a case-control study including 279 DTC cases, 165 benign thyroid disease (BTD) cases, 154 SGC cases, 61 benign salivary gland disease (BSGD) cases, and 510 controls. RESULTS: The A744G SNP genotype distribution was significantly different between subjects with SGC or BSGD and controls, while that of the A18272G SNP was significantly different between subjects with DTC or SGC and controls. Risk of SGC was significantly elevated for the 22628 heterozygous CT genotype (odds ratio [OR] = 1.5, p = .050), and risk of BSGD was elevated for the 22628 homozygous TT genotype (OR = 2.9, p = .023). CONCLUSION: Fas C22628T SNP may be associated with risk of SGC and BSGD, but none of the investigated Fas SNPs was associated with risk of DTC.
