Summaries for CNTN4 Gene

Entrez Gene Summary for CNTN4 Gene

  • This gene encodes a member of the contactin family of immunoglobulins. Contactins are axon-associated cell adhesion molecules that function in neuronal network formation and plasticity. The encoded protein is a glycosylphosphatidylinositol-anchored neuronal membrane protein that may play a role in the formation of axon connections in the developing nervous system. Deletion or mutation of this gene may play a role in 3p deletion syndrome and autism spectrum disorders. Alternative splicing results in multiple transcript variants. [provided by RefSeq, May 2011]

GeneCards Summary for CNTN4 Gene

CNTN4 (Contactin 4) is a Protein Coding gene. Diseases associated with CNTN4 include distal monosomy 3p and 3p deletion syndrome. An important paralog of this gene is PRTG.
