Genes affected

PXN (HGNC:9718): (paxillin) This gene encodes a cytoskeletal protein involved in actin-membrane attachment at sites of cell adhesion to the extracellular matrix (focal adhesion). Alternatively spliced transcript variants encoding different isoforms have been described for this gene. These isoforms exhibit different expression pattern, and have different biochemical, as well as physiological properties (PMID:9054445). [provided by RefSeq, Aug 2011]

The c.1075G>A (p.G359R) alteration is located in exon 8 (coding exon 8) of the PXN gene. This alteration results from a G to A substitution at nucleotide position 1075, causing the glycine (G) at amino acid position 359 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
