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.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 27, 2022The c.238G>A (p.D80N) alteration is located in exon 2 (coding exon 1) of the CDC42EP2 gene. This alteration results from a G to A substitution at nucleotide position 238, causing the aspartic acid (D) at amino acid position 80 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
