A 9-bp deletion homoplasmy in women with polycystic ovary syndrome revealed by mitochondrial genome-mutation screen.
Polycystic ovary syndrome (PCOS) is a complex and heterogeneous disorder presenting a challenge for clinical investigators. To investigate the association of a mitochondrial genetic basis with PCOS, we screened mutations of the whole mitochondrial genome in 57 women patients with PCOS and 38 healthy control individuals. Two-step PCR reactions were adopted to amplify and sequence the whole mitochondrial genome. A 9-bp deletion variant appeared in homoplasmy between PCOS patients and control individuals. In the 62 individuals with complete sequences, eight of 34 (23.5%) patients showed the 9-bp deletion, compared with only two of 28 (7.1%) in healthy controls. The 9-bp deletion variant in region V of mitochondrial DNA may be associated with the heterogeneous disorder PCOS.
