Genes affected

CNTNAP5 (HGNC:18748): (contactin associated protein family member 5) This gene product belongs to the neurexin family, members of which function in the vertebrate nervous system as cell adhesion molecules and receptors. This protein, like other neurexin proteins, contains epidermal growth factor repeats and laminin G domains. In addition, it includes an F5/8 type C domain, discoidin/neuropilin- and fibrinogen-like domains, and thrombospondin N-terminal-like domains. [provided by RefSeq, Jul 2008]

Ambry Genetics

Jan 10, 2023

The c.557G>A (p.R186Q) alteration is located in exon 5 (coding exon 5) of the CNTNAP5 gene. This alteration results from a G to A substitution at nucleotide position 557, causing the arginine (R) at amino acid position 186 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
