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)

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 06, 2023The c.435C>G (p.C145W) 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 435, causing the cysteine (C) at amino acid position 145 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
