Summaries for Holoprosencephaly 1

OMIM : 56 Holoprosencephaly (HPE) is the most common structural malformation of the human forebrain and occurs after failed or abbreviated midline cleavage of the developing brain during the third and fourth weeks of gestation. HPE occurs in up to 1 in 250 gestations, but only 1 in 8,000 live births (Lacbawan et al., 2009). Classically, 3 degrees of severity defined by the extent of brain malformation have been described. In the most severe form, 'alobar HPE,' there is a single ventricle and no interhemispheric fissure. The olfactory bulbs and tracts and the corpus callosum are typically absent. In 'semilobar HPE,' the most common type of HPE in neonates who survive, there is partial cortical separation with rudimentary cerebral hemispheres and a single ventricle. In 'lobar HPE,' the ventricles are separated, but there is incomplete frontal cortical separation (Corsello et al., 1990). An additional milder form, called 'middle interhemispheric variant' (MIHV) has also been delineated, in which the posterior frontal and parietal lobes are incompletely separated and the corpus callosum may be hypoplastic (Lacbawan et al., 2009). Finally, microforms of HPE include a single maxillary median incisor or hypotelorism without the typical brain malformations (summary by Mercier et al., 2011). Cohen (2001) discussed problems in the definition of holoprosencephaly, which can be viewed from 2 different perspectives: anatomic (fixed) and genetic (broad). When the main interest is description, the anatomic perspective is appropriate. In genetic perspective, a fixed definition of holoprosencephaly is not appropriate because the same mutational cause may result in either holoprosencephaly or some microform of holoprosencephaly. Cohen (2001) concluded that both fixed and broad definitions are equally valid and depend on context. Munke (1989) provided an extensive review of the etiology and pathogenesis of holoprosencephaly, emphasizing heterogeneity. See also schizencephaly (269160), which may be part of the phenotypic spectrum of HPE. (236100)

MalaCards based summary : Holoprosencephaly 1, also known as arhinencephaly, is related to holoprosencephaly 9 and anencephaly. An important gene associated with Holoprosencephaly 1 is HPE1 (Holoprosencephaly 1, Alobar), and among its related pathways/superpathways are Hedgehog signaling pathway (KEGG) and Signaling events mediated by the Hedgehog family. The drugs Cisplatin and Doxorubicin have been mentioned in the context of this disorder. Affiliated tissues include brain, parietal lobe and olfactory bulb, and related phenotypes are agenesis of corpus callosum and intellectual disability

Disease Ontology : 12 A holoprosencephaly that has material basis in variation in the chromosome region 21q22.3.
