Many HR proteins are described to be mutated in cancer samples as: Breast cancer type 1 susceptibility protein (BRCA1) in breast cancer (9), DNA repair protein RAD51 homolog 2 (RAD51B) in uterine leiomyoma (10) or ATP-dependent DNA helicase Q4 (RECQL4) in basal and squamous cell skin carcinomas (11), pointing out the relevance of the HR in the tumor development. Here, BRCA1 is linked to uterine corpus leiomyoma.
