The transcription factor GATA5, for example, is highly expressed in MRKH endometrial organoids as well as in tissue (Hentrich et al., 2020) compared to healthy controls, but has never been linked with MD anomalies, even though it is highly and dynamically expressed in the developing tissue, as revealed by a large-scale RNA-sequencing study in chicken (Roly et al., 2020). The gene discussed is GATA5; the disease is Menkes disease.
