HMGA2 and MED12 alterations frequently co-occur in uterine leiomyomas.

CONCLUSIONS: Contrary to the present findings, former studies showed that mutations in MED12 and overexpression of HMGA2 are mutually exclusive. Here, we observed that overexpression of HMGA2 mRNA in tumors measured by quantitative PCR and compared to myometrium is a common phenomenon in fibroids and is frequently associated with MED12 mutations. In addition, the common clonal origin of tumors overexpressing HMGA2 mRNA and its expression in few myometrial tissue points to HMGA2 up-regulation as an early event in leiomyoma tumorigenesis.
