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.869C>T (p.T290I) alteration is located in exon 7 (coding exon 7) of the CXADR gene. This alteration results from a C to T substitution at nucleotide position 869, causing the threonine (T) at amino acid position 290 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
