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]

Ambry Genetics

Feb 10, 2023

The c.983G>A (p.R328H) alteration is located in exon 7 (coding exon 7) of the CXADR gene. This alteration results from a G to A substitution at nucleotide position 983, causing the arginine (R) at amino acid position 328 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
