MED12 and leiomyoma: The analysis of RNA sequencing data in myometrium based on MED12 mutation status of their paired adjacent leiomyomas indicated that the expression of 6259 RNA transcripts were altered, of which 2219 RNA transcripts were up-regulated, while 4040 RNA transcripts were downregulated by 1.5-fold or greater in myometrium adjacent to MED12-mutated leiomyomas compared to myometrium adjacent to MED12 wild-type leiomyomas.
