Abstract

Flap endonuclease 1 (FEN1), a DNA repair protein, is important in preventing carcinogenesis. Two functional germ line variants ‑69G>A (rs174538) and +4150G>T (rs4246215) in the FEN1 gene have been associated with risk of various types of cancer. The aim of the present study was to evaluate the possible impact of FEN1 polymorphisms on risk of breast cancer (BC) in a sample of Iranian subjects. The FEN1 ‑69G>A and +4150G>T polymorphisms were analyzed in a case‑control study that included 266 BC patients and 225 healthy females. Polymerase chain reaction‑restriction fragment length polymorphism analysis was used to genotype the variants. The findings demonstrated that the FEN1 ‑69G>A and +4150G>T polymorphisms were not associated with BC risk in co‑dominant, dominant and recessive inheritance models. The findings indicated that GG/GT, GA/GG and GA/TT genotypes significantly decreased the risk of BC when compared with ‑69GG/+4150GG. Furthermore, haplotype analysis indicated that ‑69G/+4150T as well as ‑69A/+4150G significantly decreased the risk of BC compared with ‑69G/+4150G. Thus, these findings demonstrated that haplotypes of FEN1 ‑69G>A and +4150G>T polymorphisms decreased the risk of BC in an Iranian population. Further studies with larger sample sizes and different ethnicities are required to validate the present findings.
