Summaries for Holoprosencephaly 9

OMIM : 57 Holoprosencephaly-9 refers to a disorder characterized by a wide phenotypic spectrum of brain developmental defects, with or without overt forebrain cleavage abnormalities. It usually includes midline craniofacial anomalies involving the first branchial arch and/or orbits, pituitary hypoplasia with panhypopituitarism, and postaxial polydactyly. The disorder shows incomplete penetrance and variable expressivity (summary by Roessler et al., 2003 and Bertolacini et al., 2012). For general phenotypic information and a discussion of genetic heterogeneity of holoprosencephaly, see HPE1 (236100). (610829)

MalaCards based summary : Holoprosencephaly 9, also known as pituitary anomalies with holoprosencephaly-like features, is related to culler-jones syndrome, and has symptoms including seizures An important gene associated with Holoprosencephaly 9 is GLI2 (GLI Family Zinc Finger 2). Affiliated tissues include pituitary and brain, and related phenotypes are malar flattening and hydrocephalus

Disease Ontology : 12 A holoprosencephaly that has material basis in heterozygous mutation in the GLI2 gene on chromosome 2q14.

UniProtKB/Swiss-Prot : 75 Holoprosencephaly 9: A structural anomaly of the brain, in which the developing forebrain fails to correctly separate into right and left hemispheres. Holoprosencephaly is genetically heterogeneous and associated with several distinct facies and phenotypic variability. Holoprosencephaly type 9 is characterized by defective anterior pituitary formation and pan-hypopituitarism, with or without overt forebrain cleavage abnormalities, and holoprosencephaly-like midfacial hypoplasia.
