Genes affected

CNTN4 (HGNC:2174): (contactin 4) 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]

The c.31C>A (p.Q11K) alteration is located in exon 3 (coding exon 1) of the CNTN4 gene. This alteration results from a C to A substitution at nucleotide position 31, causing the glutamine (Q) at amino acid position 11 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
