Specifically, LHX1 (LIM homeobox protein 1) and HNF1B (hepatocyte nuclear factor 1B; also known as TCF2) genes seem to be important candidates based on the prevalence of their variants in MRKH patients and their established roles in the development of the reproductive and urinary system [28]. The gene discussed is HNF1B; the disease is Mayer-Rokitansky-Kuster-Hauser syndrome.
