    Abstract:
    Accumulated evidence have proposed that single nucleotide polymorphisms (SNPs) in microRNAs (miRNAs) are connected to breast cancer (BC) risk. We have done a case-control study with 258 BC patients and 209 control women to examine the potential association of Hsa-mir-603 rs11014002 C>T polymorphisms with BC susceptibility. The polymorphisms were genotyped by polymerase chain reaction restriction fragment length polymorphism (PCR-RFLP) method. Our findings showed that the rs11014002 C>T variant was not associated with an increased risk of BC in codominant (OR=0.67, 95%CI=0.42-1.08, P=0.121, CT vs CC; and OR=0.18, 95%CI=0.02-1.67, P=0.170, TT vs CC), dominant (OR=0.64, 95%CI=0.41-1.01, P=0.062, CT+TT vs CC), and recessive (OR=0.20, 95%CI=0.02-1.81, P=0.178, TT vs CC+CT) inheritance models tested. While, the T allele significantly decreased the risk of BC (OR= 0.63; 95% CI =0.41-0.95; P=0.032) compared to C allele. In conclusion, the findings indicated that Mir603 rs11014002 T allele might contribute to decrease the risk of BC in a sample of Iranian population. Further studies with larger sample sizes and different ethnicities are warranted to confirm our findings.
