Genes affected

CXADR (HGNC:2559): (CXADR Ig-like cell adhesion molecule) The protein encoded by this gene is a type I membrane receptor for group B coxsackieviruses and subgroup C adenoviruses. Several transcript variants encoding different isoforms have been found for this gene. Pseudogenes of this gene are found on chromosomes 15, 18, and 21. [provided by RefSeq, May 2011]

ACMG classification

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

• BP4: Computational evidence support a benign effect (MetaRNN=0.0011855066).
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.318 is higher than 0.05.
