Genes affected

CNTN5 (HGNC:2175): (contactin 5) The protein encoded by this gene is a member of the immunoglobulin superfamily, and contactin family, which mediate cell surface interactions during nervous system development. This protein is a glycosylphosphatidylinositol (GPI)-anchored neuronal membrane protein that functions as a cell adhesion molecule. It may play a role in the formation of axon connections in the developing nervous system. Alternatively spliced transcript variants encoding different isoforms have been described for this gene.

The c.487A>G (p.S163G) alteration is located in exon 1 (coding exon 1) of the CNTN5 gene. This alteration results from a A to G substitution at nucleotide position 487, causing the serine (S) at amino acid position 163 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
