Genes affected

WIPF2 (HGNC:30923): (WAS/WASL interacting protein family member 2) This gene encodes a WASP interacting protein (WIP)-related protein. It has been shown that this protein has a role in the WASP-mediated organization of the actin cytoskeleton and that this protein is a potential link between the activated platelet-derived growth factor receptor and the actin polymerization machinery.

The c.107G>T (p.G36V) alteration is located in exon 3 (coding exon 2) of the WIPF2 gene. This alteration results from a G to T substitution at nucleotide position 107, causing the glycine (G) at amino acid position 36 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
