Peer Review Report For: rs4889 and rs5782018 polymorphisms of KISS1 gene as genetic predisposing factor for PCOS in Indonesian women [version 1; peer review: 1 approved, 1 approved with reservations]

* Background A disruption in the function of the HPG axis in PCOS causes increased frequency and amplitude of gonadotropin-releasing hormone (GnRH) pulsatility in the hypothalamus. Single nucleotide polymorphisms (SNPs) in the KISS1 gene may contribute to this dysregulation and promote disease development. The present study aims to determine the impact of KISS1 gene polymorphisms and haplotypes on the development of PCOS. Methods A cross-sectional study was conducted at Yasmin Clinic, dr. Cipto Mangunkusumo General Hospital, Indonesia, involving 60 women with PCOS and 60 healthy controls. Hormonal levels were assessed using ELISA, and genomic DNA was analyzed by Sanger sequencing. Demographic data were compared using independent t-tests, and chi-square tests were used for genotype and allele frequency analysis. Results The genotypic distribution of rs4889 was significantly different between the PCOS and control groups (p
