Sequencing chromatograms confirming genotypes at rs17134592. Representative Sanger sequencing chromatograms demonstrate the three genotypes observed for rs17134592 in the AKR1C4 gene. The CC genotype shows a single peak for cytosine (C) at the polymorphic site, the CG genotype exhibits overlapping peaks for cytosine (C) and guanine (G), and the GG genotype presents a single peak for guanine (G).
