Premature ovarian failure and androgen receptor gene CAG repeat lengths weighted by X chromosome inactivation patterns
Received 12 September 2007; received in revised form 28 November 2007; accepted 28 November 2007. published online 18 February 2008.
The CAG repeat lengths weighted by X-inactivation ratios were significantly shorter in 58 Japanese patients with premature ovarian failure (POF) than in 42 age-matched control females with normal menses. The results suggest that short CAG repeats with a relatively high androgen receptor function may constitute a susceptibility factor for the development of POF.
