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]

Collection Method: clinical testing

The c.1520C>T (p.T507M) alteration is located in exon 12 (coding exon 12) of the PXN gene. This alteration results from a C to T substitution at nucleotide position 1520, causing the threonine (T) at amino acid position 507 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
