Summaries for Holoprosencephaly 7

OMIM : 58 Holoprosencephaly (HPE) is the most commonly occurring congenital structural forebrain anomaly in humans. HPE is associated with mental retardation and craniofacial malformations. Considerable heterogeneity in the genetic causes of HPE has been demonstrated (Ming et al., 2002). (610828)

MalaCards based summary : Holoprosencephaly 7, is also known as hpe7, and has symptoms including seizures An important gene associated with Holoprosencephaly 7 is PTCH1 (Patched 1). Affiliated tissues include brain, and related phenotypes are omphalocele and depressed nasal tip

Disease Ontology : 12 A holoprosencephaly that has material basis in heterozygous mutation in the PTCH1 gene on chromosome 9q22.

UniProtKB/Swiss-Prot : 76 Holoprosencephaly 7: 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.
