Genes affected

CDC42EP4 (HGNC:17147): (CDC42 effector protein 4) The product of this gene is a member of the CDC42-binding protein family. Members of this family interact with Rho family GTPases and regulate the organization of the actin cytoskeleton. This protein has been shown to bind both CDC42 and TC10 GTPases in a GTP-dependent manner. When overexpressed in fibroblasts, this protein was able to induce pseudopodia formation, which suggested a role in inducing actin filament assembly and cell shape control.

The c.606T>A (p.H202Q) alteration is located in exon 2 (coding exon 1) of the CDC42EP4 gene. This alteration results from a T to A substitution at nucleotide position 606, causing the histidine (H) at amino acid position 202 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
