Genes affected
CDC42EP1 (HGNC:17014): (CDC42 effector protein 1) CDC42 is a member of the Rho GTPase family that regulates multiple cellular activities, including actin polymerization. The protein encoded by this gene is a CDC42 binding protein that mediates actin cytoskeleton reorganization at the plasma membrane. This protein is secreted and is primarily found in bone marrow.

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 23, 2023The c.589C>T (p.R197C) alteration is located in exon 3 (coding exon 2) of the CDC42EP1 gene. This alteration results from a C to T substitution at nucleotide position 589, causing the arginine (R) at amino acid position 197 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
