In addition, a study conducted on a population of Indian women, among 267 cases diagnosed with polycystic ovary syndrome in comparison to 275 healthy controls, the CYP11A1 polymorphic pentanucleotide repeat was analysed by the PCR-PAGE technique, which showed that the increasing recurrence of polymorphisms could be a biomarker for the risk of PCOS. The gene discussed is CYP11A1; the disease is polycystic ovary syndrome.
