Genes affected

PVR (HGNC:9705): (PVR cell adhesion molecule) The protein encoded by this gene is a transmembrane glycoprotein belonging to the immunoglobulin superfamily. The external domain mediates cell attachment to the extracellular matrix molecule vitronectin, while its intracellular domain interacts with the dynein light chain Tctex-1/DYNLT1. The gene is specific to the primate lineage, and serves as a cellular receptor for poliovirus in the first step of poliovirus replication. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Oct 2008]

The c.179A>G (p.H60R) alteration is located in exon 2 (coding exon 2) of the PVR gene. This alteration results from a A to G substitution at nucleotide position 179, causing the histidine (H) at amino acid position 60 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
