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]
CDC42EP3-AS1 (HGNC:56370): (CDC42EP3 antisense RNA 1)

The c.277T>C (p.S93P) alteration is located in exon 2 (coding exon 1) of the CDC42EP3 gene. This alteration results from a T to C substitution at nucleotide position 277, causing the serine (S) at amino acid position 93 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
