Germ line mutations in DNA repair system-related genes are associated with an increased risk of BC. This study aims to evaluate the frequencies of single nucleotide polymorphisms (SNPs) in the BRCA1, BRCA2, and PALB2 genes in patients with BC from a subset of the Iranian population in the western part of Iran.</p><p><strong>Methods: </strong>Blood samples were collected from 335 patients with BC and 354 healthy matched volunteers. Genomic DNA was extracted using the salting-out method and, after quality control, was genotyped using the multiplex TaqMan allelic discrimination assay for three SNPs: rs80359550 (6174 delT) in the BRCA2 gene, rs180177102 in the PALB2 gene, and rs386833395 (185delAG) in the BRCA1 gene. Statistical analysis was performed to examine allele frequency, odds ratio, and relative risk (genetic association) in a retrospective case-control study.</p><p><strong>Results: </strong>The data showed no association between rs386833395 and BC risk in the studied population (odds ratio = 1), whereas rs80359550 and rs180177102 polymorphisms were strongly associated with BC risk in patients (odds ratio = 0.01 for both, with p-values of 0.011 and 0.021, respectively).</p><p><strong>Conclusions: </strong>Our findings suggest no significant association between the rs386833395 polymorphism and BC risk in the Iranian Kurdish population, while rs80359550 and rs180177102 polymorphisms were strongly associated with BC. However, the study has several limitations, including its retrospective design, a relatively small sample size, and the potential lack of generalizability to other ethnic groups within Iran. Future studies involving larger cohorts and more diverse populations are needed to confirm these results.</p>","PeriodicalId":55058,"journal":{"name":"Hereditary Cancer in Clinical Practice","volume":"23 1","pages":"12"},"PeriodicalIF":2.0,"publicationDate":"2025-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11954309/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143744455","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
