Summaries for Lissencephaly, X-Linked, 2

OMIM : 58 X-linked lissencephaly-2 (LISX2) is a developmental disorder characterized by structural brain anomalies, early-onset intractable seizures, severe psychomotor retardation, and ambiguous genitalia. Males are severely affected and often die within the first days or months of life, whereas females may be unaffected or have a milder phenotype (Bonneau et al., 2002). LISX2 is part of a phenotypic spectrum of disorders caused by mutation in the ARX gene comprising a nearly continuous series of developmental disorders ranging from hydranencephaly and lissencephaly to Proud syndrome (300004) to infantile spasms without brain malformations (EIEE1; 308350) to syndromic (309510) and nonsyndromic (300419) mental retardation (Kato et al., 2004; Wallerstein et al., 2008). For a general phenotypic description and a discussion of genetic heterogeneity of lissencephaly, see LIS1 (607432). (300215)

MalaCards based summary : Lissencephaly, X-Linked, 2, also known as hydranencephaly with abnormal genitalia, is related to x-linked lissencephaly with abnormal genitalia and lissencephaly, and has symptoms including snoring and thick skin. An important gene associated with Lissencephaly, X-Linked, 2 is ARX (Aristaless Related Homeobox). Affiliated tissues include brain, skin and testes, and related phenotypes are agenesis of corpus callosum and seizures

UniProtKB/Swiss-Prot : 76 Lissencephaly, X-linked 2: A classic type lissencephaly associated with abnormal genitalia. Patients have severe congenital or postnatal microcephaly, lissencephaly, agenesis of the corpus callosum, neonatal-onset intractable epilepsy, poor temperature regulation, chronic diarrhea, and ambiguous or underdeveloped genitalia.
