Consistent with these findings, recent population-based research has also revealed relationships between CYP3A4 and CYP3A5 genotypes and a higher risk of developing prostate cancer in a Bangladeshi population, linked to the presence of *1A/1B and *1B/1B genotypes of CYP3A4 as well as to the CYP3A5 gene’s *1/3 and *3/3 genotype [41]. This evidence concerns the gene CYP3A5 and prostate cancer.
