Thirty clinically diagnosed breast cancer patients, all women, were enrolled in the current study, and high\u2010quality DNA was extracted from peripheral blood samples. Two of the twenty\u2010five successfully sequenced samples had a homozygous missense variant (c.2312T\u2009&gt;\u2009C: p.Leu771Ser) detected by Sanger sequencing after PCR amplification. Upon investigation in the ClinVar database, the identified variant showed conflicting interpretations of pathogenicity. Demographic data highlighted an early disease onset, showing that 56% of patients were under 50\u2009years of age. The need for genetic screening was further supported by the fact that 24% of the patients had a positive family history of cancer.
