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]

The c.295A>G (p.K99E) alteration is located in exon 3 (coding exon 3) of the CXADR gene. This alteration results from a A to G substitution at nucleotide position 295, causing the lysine (K) at amino acid position 99 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
