DNA variants in leiomyomas were confined to exon 2 of MED12.

aSplice site variants were located in intron 1 within 10 base-pairs of the intron 1-exon 2 junction.bVariants were classified as a single nucleotide variant (SNV) or a deletion/insertion-deletion (indel).cThe number of leiomyomas with each specific variant is followed in parentheses by the percentage of the total number of leiomyomas under study (148) and the percentage of the total number of mutated leiomyomas (100), respectively.
