No evidence for the role of somatic mutations and promoter hypermethylation of FH gene in the tumorigenesis of nonsyndromic uterine leiomyomas.

Fumarate hydratase (FH) gene is reported to have specific involvement in syndromic uterine tumors, but its role in nonsyndromic forms is still unclear. Hence, the present study has aimed to screen the role of promoter methylation status and mutations in exon 2 and 7 regions of FH gene in the genesis of nonsyndromic uterine leiomyomas. Leiomyoma and myometrium tissues were collected from 85 hysterectomized uterine specimens.
