Summaries for X-Linked Lissencephaly with Abnormal Genitalia

NIH Rare Diseases : 53 The following summary is from Orphanet, a European reference portal for information on rare diseases and orphan drugs.Orpha Number: 452Disease definitionX-linked lissencephaly with abnormal genitalia (XLAG) is a rare, genetic, central nervous system malformation disorder characterized, in males, by lissencephaly (with posterior predominance and moderately thickened cortex), complete absence of corpus callosum, neonatal-onset (mainly perinatal) intractable seizures, postnatal microcephaly, severe hypotonia, poor responsiveness and hypogonadism (micropenis, hypospadias, cryptorchidism, small scrotal sac). Defective temperature regulation and chronic diarrhea may be additionally observed.Clinical descriptionXLAG differs considerably from classical lissencephaly, as the resulting cortical thickness is only 6-7 mm in XLAG, rather than 15-20 mm seen in classical lissencephaly due to mutations of the PAFAH1B1 or DCX genes.EtiologyIn 2002, mutations in the X-linked aristaless-related homeobox gene (ARX; Xp21.3) were identified in individuals with XLAG and in some of their female relatives. Mouse Arx and human ARX are highly expressed in both dorsal and ventral telencephalon, including the neocortical ventricular zone and germinal zone of the ganglionic eminence, with less intense signals in the subventricular zone, cortical plate, hippocampus, basal ganglia and ventral thalamus. Arx-deficient mice showed deficient tangential migration and abnormal differentiation of GABAergic interneurons in the ganglionic eminence and neocortex, as well as abnormal testicular differentiation. These characteristics include some of the clinical features of XLAG in humans. The ARX mutations in XLAG patients were predominantly premature termination mutations (large deletions, frameshift, nonsense mutations, splice site mutations) while the missense mutations were less common and located essentially in the homeobox domain. Patients carrying nonconservative missense mutations within the homeobox, showed less severe XLAG, while conservative substitution in the homeodomain caused Proud syndrome (ACC with abnormal genitalia). A non conservative missense mutation near the C-terminal aristaless domain caused unusually severe XLAG with microcephaly and mild cerebellar hypoplasia. The ARX mutations are also associated with a spectrum of milder phenotypes, without macroscopic malformations of the brain, such as X-linked infantile spasms, a syndrome featuring mental retardation associated with distal dystonic movements (Partington syndrome; see this term), autistic features and nonsyndromicintellectual deficit.Visit the Orphanet disease page for more resources.

MalaCards based summary : X-Linked Lissencephaly with Abnormal Genitalia, also known as x-linked lissencephaly with ambiguous genitalia, is related to chromosome xq26.3 duplication syndrome and lissencephaly, x-linked, 2, and has symptoms including thick skin and snoring. An important gene associated with X-Linked Lissencephaly with Abnormal Genitalia is ARX (Aristaless Related Homeobox). Affiliated tissues include brain, cortex and thalamus, and related phenotypes are agenesis of corpus callosum and intellectual disability

Genetics Home Reference : 25 X-linked lissencephaly with abnormal genitalia (XLAG) is a condition that affects the development of the brain and genitalia. It occurs most often in males.
