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]

ACMG classification

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-1.03).
• BA1: GnomAd4 highest subpopulation (SAS) allele frequency at 95% confidence interval = 0.874 is higher than 0.05.
