Mutant Forkhead L2 (FOXL2) Proteins Associated with Premature Ovarian Failure (POF) Dimerize with Wild-Type FOXL2, Leading to Altered Regulation of Genes Associated with Granulosa Cell Differentiation

Abstract excerpt

Premature ovarian failure in the autosomal dominant disorder blepharophimosis-ptosis-epicanthus inversus is due to mutations in the gene encoding Forkhead L2 (FOXL2), producing putative truncated proteins. We previously demonstrated that FOXL2 is a transcriptional repressor of the steroidogenic acute regulatory (StAR), P450SCC (CYP11A), P450aromatase (CYP19), and cyclin D2 (CCND2) genes, markers of ovarian...
