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 GeneticsSep 25, 2023The c.748C>G (p.L250V) alteration is located in exon 6 (coding exon 6) of the CXADR gene. This alteration results from a C to G substitution at nucleotide position 748, causing the leucine (L) at amino acid position 250 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
