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.

The c.373C>T (p.L125F) alteration is located in exon 2 (coding exon 1) of the CDC42EP1 gene. This alteration results from a C to T substitution at nucleotide position 373, causing the leucine (L) at amino acid position 125 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
