摘要: In type I blepharophimosis/ptosis/epicanthus inversus syndrome (BPES), eyelid abnormalities are associated with ovarian failure. Type II BPES shows only the defects, but both types map to chromosome 3q23. We have positionally cloned a novel, putative winged helix/forkhead transcription factor gene, FOXL2, that is mutated produce truncated proteins in families and larger II. Consistent an involvement those tissues, FOXL2 selectively expressed mesenchyme of developing mouse eyelids adult follicles; humans, it appears predominantly ovary. represents candidate gene for polled/intersex XX sex-reversal goat.
