Functional genetic variation within CYP3A5 can alter enzyme activity and may consequently modify individual susceptibility to malignancy. The contribution of CYP3A5 genetic variation to breast cancer risk, as well as its potential relevance to tumor biology, remains inadequately characterized in the Bangladeshi population.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Objective<\/jats:title>\n                    <jats:p>The current study investigated the relationship of CYP3A5\u22173 (rs776746) polymorphism with the susceptibility of breast cancer and explored its relationship with immune infiltration and survival outcomes.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>The study was conducted as a case\u2013control study including 170 breast cancer patients and 170 age\u2010matched healthy individuals. CYP3A5\u22173 (rs776746) genotypes were determined using polymerase chain reaction\u2013restriction fragment length polymorphism (PCR\u2013RFLP) analysis. Genetic associations were calculated using odds ratios (ORs) with 95% confidence intervals (CIs). Complementary computational analyses evaluated the association of CYP3A5 expression with tumor immune\u2010cell infiltration using TIMER2.0 and examined its prognostic relevance through survival data from TCGA accessed via UALCAN.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      CYP3A5\u22173 genotype frequencies differed significantly between cases and controls. Compared with the wild\u2010type genotype (\u22171\/\u22171), the heterozygote (\u22171\/\u22173) genotype (OR\u2009=\u20092.57;\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.0016), mutant homozygote (\u22173\/\u22173) (OR\u2009=\u20091.78;\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.0376), and combined variant genotypes (\u22171\/\u22173\u2009+\u2009\u22173\/\u22173) (OR\u2009=\u20092.11;\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.0010) were associated with increased breast cancer risk. The CYP3A5\u22173 allele was more prevalent in cases than controls (36% vs. 25%; OR\u2009=\u20091.75;\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.0009). In silico analysis showed that CYP3A5 expression was positively correlated with immune\u2010cell infiltration of several immune cells. The elevated expression of CYP3A5 was linked to poorer survival in selected clinical subgroups.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>The findings indicate that the CYP3A5\u22173 polymorphism may contribute to genetic susceptibility to breast cancer among Bangladeshi women.
