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.56T>C (p.L19P) alteration is located in exon 1 (coding exon 1) of the PVR gene. This alteration results from a T to C substitution at nucleotide position 56, causing the leucine (L) at amino acid position 19 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
