Genes affected

PAK2 (HGNC:8591): (p21 (RAC1) activated kinase 2) The p21 activated kinases (PAK) are critical effectors that link Rho GTPases to cytoskeleton reorganization and nuclear signaling. The PAK proteins are a family of serine/threonine kinases that serve as targets for the small GTP binding proteins, CDC42 and RAC1, and have been implicated in a wide range of biological activities. The protein encoded by this gene is activated by proteolytic cleavage during caspase-mediated apoptosis, and may play a role in regulating the apoptotic events in the dying cell.

The c.1451A>T (p.D484V) alteration is located in exon 14 (coding exon 13) of the PAK2 gene. This alteration results from a A to T substitution at nucleotide position 1451, causing the aspartic acid (D) at amino acid position 484 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
