Dasgupta et al. sequenced 250 PCOS women and 299 controls for PPARγ exon 2 and 6 in order to identify distinct single nucleotide polymorphisms in these exonic regions specific to the South Indian population and remarked that the PPARγ exon 2 Ala allele and exon 6 His447His T allele were significantly more in the controls than in the PCOS population. Here, PPARG is linked to polycystic ovary syndrome.
