Entrez Gene summary for OCLN Gene:

This gene encodes an integral membrane protein that is required for cytokine-induced regulation of the tight

junction paracellular permeability barrier. Mutations in this gene are thought to be a cause of band-like

calcification with simplified gyration and polymicrogyria (BLC-PMG), an autosomal recessive neurologic disorder

that is also known as pseudo-TORCH syndrome. Alternative splicing results in multiple transcript variants. A

related pseudogene is present 1.5 Mb downstream on the q arm of chromosome 5. (provided by RefSeq, Apr 2011)

GeneCards Summary for OCLN Gene:

OCLN (occludin) is a protein-coding gene. Diseases associated with OCLN include pseudo-torch syndrome, and torch syndrome. GO annotations related to this gene include structural molecule activity.

UniProtKB/Swiss-Prot: OCLN_HUMAN, Q16625

Function: May play a role in the formation and regulation of the tight junction (TJ) paracellular permeability

barrier. It is able to induce adhesion when expressed in cells lacking tight junctions

Band-like calcification with simplified gyration and polymicrogyria (BLCPMG) [MIM:251290]: A neurologic

disorder with characteristic clinical and neuroradiologic features that mimic intrauterine TORCH infection in the

absence of evidence of infection. Affected individuals have congenital microcephaly, intracranial calcifications,

and severe developmental delay. Note=The disease is caused by mutations affecting the gene represented in this
