Genes affected

CDC42EP2 (HGNC:16263): (CDC42 effector protein 2) CDC42, a small Rho GTPase, regulates the formation of F-actin-containing structures through its interaction with the downstream effector proteins. The protein encoded by this gene is a member of the Borg family of CDC42 effector proteins. Borg family proteins contain a CRIB (Cdc42/Rac interactive-binding) domain. They bind to, and negatively regulate the function of CDC42. Coexpression of this protein with CDC42 suggested a role of this protein in actin filament assembly and cell shape control.

The c.166T>C (p.S56P) alteration is located in exon 2 (coding exon 1) of the CDC42EP2 gene. This alteration results from a T to C substitution at nucleotide position 166, causing the serine (S) at amino acid position 56 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
