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.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 22, 2021The c.215C>A (p.A72E) alteration is located in exon 1 (coding exon 1) of the CNTN5 gene. This alteration results from a C to A substitution at nucleotide position 215, causing the alanine (A) at amino acid position 72 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
