Functioni

Neural cell adhesion molecule involved in the dynamics of cell adhesion and in the generation of transmembrane signals at tyrosine kinase receptors. During brain development, critical in multiple processes, including neuronal migration, axonal growth and fasciculation, and synaptogenesis. In the mature brain, plays a role in the dynamics of neuronal structure and function, including synaptic plasticity.Curated1 Publication

Involvement in diseasei

Hydrocephalus due to stenosis of the aqueduct of Sylvius (HSAS)22 Publications
The disease is caused by mutations affecting the gene represented in this entry. L1CAM mutations have also been found in few patients affected by hydrocephalus with Hirschsprung disease, suggesting a role of this gene acting either in a direct or indirect way in the pathogenesis of Hirschsprung disease (PubMed:22344793).1 Publication
Disease descriptionHydrocephalus is a condition in which abnormal accumulation of cerebrospinal fluid in the brain causes increased intracranial pressure inside the skull. This is usually due to blockage of cerebrospinal fluid outflow in the brain ventricles or in the subarachnoid space at the base of the brain. In children is typically characterized by enlargement of the head, prominence of the forehead, brain atrophy, mental deterioration, and convulsions. In adults the syndrome includes incontinence, imbalance, and dementia. HSAS is characterized by mental retardation and enlarged brain ventricles.

Mental retardation, aphasia, shuffling gait, and adducted thumbs syndrome (MASA)21 Publications
The disease is caused by mutations affecting the gene represented in this entry.
Disease descriptionAn X-linked recessive syndrome with a highly variable clinical spectrum. Main clinical features include spasticity and hyperreflexia of lower limbs, shuffling gait, mental retardation, aphasia and adducted thumbs. The features of spasticity have been referred to as complicated spastic paraplegia type 1 (SPG1). Some patients manifest corpus callosum hypoplasia and hydrocephalus. Inter- and intrafamilial variability is very wide, such that patients with hydrocephalus, MASA, SPG1, and agenesis of corpus callosum can be present within the same family.

Defects in L1CAM may contribute to Hirschsprung disease by modifying the effects of Hirschsprung disease-associated genes to cause intestinal aganglionosis.1 Publication
Agenesis of the corpus callosum, X-linked, partial (ACCPX)1 Publication
The disease is caused by mutations affecting the gene represented in this entry.
Disease descriptionA syndrome characterized by partial corpus callosum agenesis, hypoplasia of inferior vermis and cerebellum, mental retardation, seizures and spasticity. Other features include microcephaly, unusual facies, and Hirschsprung disease in some patients.
See also OMIM:304100
Defects in L1CAM are associated with a wide phenotypic spectrum which varies from severe hydrocephalus and prenatal death (HSAS) to a milder phenotype (MASA). These variations may even occur within the same family. Due to the overlap of phenotypes between HSAS and MASA, many authors use the general concept of L1 syndrome which covers both ends of the spectrum.3 Publications
