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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 26, 2023The c.790C>T (p.R264C) alteration is located in exon 6 (coding exon 6) of the CXADR gene. This alteration results from a C to T substitution at nucleotide position 790, causing the arginine (R) at amino acid position 264 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
