Summaries for Lissencephaly, X-Linked, 1

UniProtKB/Swiss-Prot : 75 Lissencephaly, X-linked 1: A classic lissencephaly characterized by mental retardation and seizures that are more severe in male patients. Affected boys show an abnormally thick cortex with absent or severely reduced gyri. Clinical manifestations include feeding problems, abnormal muscular tone, seizures and severe to profound psychomotor retardation. Female patients display a less severe phenotype referred to as 'doublecortex'. Subcortical band heterotopia X-linked: SBHX is a mild brain malformation of the lissencephaly spectrum. It is characterized by bilateral and symmetric plates or bands of gray matter found in the central white matter between the cortex and cerebral ventricles, cerebral convolutions usually appearing normal.

MalaCards based summary : Lissencephaly, X-Linked, 1, also known as lissencephaly, x-linked, is related to lissencephaly 1 and band heterotopia, and has symptoms including ataxia and seizures. An important gene associated with Lissencephaly, X-Linked, 1 is DCX (Doublecortin), and among its related pathways/superpathways are Cytoskeletal Signaling and Lissencephaly gene (LIS1) in neuronal migration and development. Affiliated tissues include cortex, brain and testes, and related phenotypes are seizures and muscular hypotonia

OMIM : 57 Lissencephaly ('smooth brain') results from migrational arrest of cortical neurons short of their normal destination, and can result in profound mental retardation and seizures. In X-linked lissencephaly-1, affected males generally have more a severe phenotype compared to females. DCX mutations cause classic lissencephaly with mental retardation in hemizygous males and a milder phenotype known as subcortical band heterotopia in females, sometimes in the same family. The subcortical lamina heterotopia found in heterozygous females is also referred to as 'double cortex' (DC) syndrome (des Portes et al., 1997). There are several X-linked loci that affect neuronal migration, including the Aicardi locus (304050). (300067)
