Genes affected
CDC42EP3 (HGNC:16943): (CDC42 effector protein 3) This gene encodes a member of a small family of guanosine triphosphate (GTP) metabolizing proteins that contain a CRIB (Cdc42, Rac interactive binding) domain. Members of this family of proteins act as effectors of CDC42 function. The encoded protein is involved in actin cytoskeleton re-organization during cell shape changes, including pseudopodia formation. A pseudogene of this gene is found on chromosome 19. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jul 2012]

The c.623C>G (p.P208R) alteration is located in exon 2 (coding exon 1) of the CDC42EP3 gene. This alteration results from a C to G substitution at nucleotide position 623, causing the proline (P) at amino acid position 208 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
