Summaries for TM4SF20 Gene

Entrez Gene Summary for TM4SF20 Gene

  • The protein encoded by this gene is a member of the four-transmembrane L6 superfamily. Members of this family function in various cellular processes including cell proliferation, motility, and adhesion via their interactions with integrins. In human brain tissue, this gene is expressed at high levels in the parietal lobe, occipital lobe, hippocampus, pons, white matter, corpus callosum, and cerebellum. Knockout of the homologous gene in mouse results in a neurobehavioral phenotype with suggested enhanced motor coordination. A deletion mutation in the human gene is associated with specific language impairment-5. [provided by RefSeq, Jul 2016]

  • Specific language impairment 5 (SLI5) [MIM:615432]: A disorder characterized by a delay in early speech acquisition. It is usually associated with cerebral white matter abnormalities on brain MRI. Some individuals may show disorders in communication, consistent with autism spectrum disorder, or global developmental delay, although others ultimately show normal cognitive function. Penetrance is incomplete and expressivity is variable. {ECO:0000269 PubMed:23810381}. Note=The disease is caused by mutations affecting the gene represented in this entry.
