Wiedemann-Steiner Syndrome, also known as hypertrichosis-short stature-facial dysmorphism-developmental delay syndrome, is related to kabuki syndrome 1 and hypertrichosis. An important gene associated with Wiedemann-Steiner Syndrome is KMT2A (Lysine Methyltransferase 2A), and among its related pathways/superpathways are DNA IR-double strand breaks and cellular response via ATM and Retinoblastoma gene in cancer. Affiliated tissues include eye and bone, and related phenotypes are delayed speech and language development and dysphagia
