Kinase module of Mediator complex ('CDK8 submodule') consists of four subunits: CDK8, Cyclin C, MED12, and MED13. Recently, we reported recurrent MED12 mutations in 70% of uterine leiomyomas. The aim of this study was to analyse whether mutations in other components of the module contribute to the development of these lesions. Mutation screening of altogether 70 MED12 mutation-negative uterine leiomyomas was carried out by direct sequencing. None of the tumours displayed somatic mutations in the coding regions of CDK8/CDK19, CCNC, or MED13. Mutations in CDK8/CDK19, CCNC, and MED13 do not frequently contribute to genesis of uterine leiomyomas.
