DGAT1 and polycystic ovary syndrome: Based on the above results, Sanger sequencing and the PubMed, NCBI, and other databases, we selected some genes highly likely to be associated with PCOS in this family (Table 6): DGAT1, EHMT1, KDR, LAMTOR1, SEC13, SETD2, and TGF-β1. In order to further explore the association between susceptibility genes and PCOS, we set the inclusion criteria for the following genes: (a) In The Genome Aggregation Database, the allele frequency of the mutated base (GnomAD_ALL_AF) was greater than 0.0002.
