Summaries for Kabuki Syndrome 2

OMIM : 58 Kabuki syndrome is a congenital mental retardation syndrome with additional features, including postnatal dwarfism, a peculiar facies characterized by long palpebral fissures with eversion of the lateral third of the lower eyelids (reminiscent of the make-up of actors of Kabuki, a Japanese traditional theatrical form), a broad and depressed nasal tip, large prominent earlobes, a cleft or high-arched palate, scoliosis, short fifth finger, persistence of fingerpads, radiographic abnormalities of the vertebrae, hands, and hip joints, and recurrent otitis media in infancy (Niikawa et al., 1981). For a discussion of genetic heterogeneity of Kabuki syndrome, see KABUK1 (147920). (300867)

MalaCards based summary : Kabuki Syndrome 2, also known as kabuk2, is related to kabuki syndrome 1 and hyperinsulinism, and has symptoms including seizures An important gene associated with Kabuki Syndrome 2 is KDM6A (Lysine Demethylase 6A). Affiliated tissues include heart and breast, and related phenotypes are atrial septal defect and coarctation of aorta
