Genes affected

PARVB (HGNC:14653): (parvin beta) This gene encodes a member of the parvin family of actin-binding proteins, which play a role in cytoskeleton organization and cell adhesion. These proteins are associated with focal contacts and contain calponin homology domains that bind to actin filaments. This family member binds to alphaPIX and alpha-actinin, and it can inhibit the activity of integrin-linked kinase. This protein also functions in tumor suppression. Alternative splicing of this gene results in multiple transcript variants. [provided by RefSeq, Aug 2011]

The c.806G>A (p.R269Q) alteration is located in exon 9 (coding exon 9) of the PARVB gene. This alteration results from a G to A substitution at nucleotide position 806, causing the arginine (R) at amino acid position 269 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
