FAS and breast carcinoma: In neoplasias, the polymorphic alleles for FAS rs1800682 (A/G) and FASL rs763110 (C/T) represented a protective effect against gastric cancer [43]; the FAS rs1800682 (A/G), FASL rs5030772 (A/G), and FASL rs763110 (C/T) polymorphisms were associated with the risk of breast cancer [44,45], and the wild-type genotype for FASL rs763110 (C/T) was considered a risk factor for prostate pathologies [46].
