Genes affected

CDC42BPA (HGNC:1737): (CDC42 binding protein kinase alpha) The protein encoded by this gene is a member of the serine/threonine protein kinase family. This kinase contains multiple functional domains. Its kinase domain is highly similar to that of the myotonic dystrophy protein kinase (DMPK). This kinase also contains a Rac interactive binding (CRIB) domain, and has been shown to bind CDC42. It may function as a CDC42 downstream effector mediating CDC42 induced peripheral actin formation, and promoting cytoskeletal reorganization. Multiple alternatively spliced transcript variants have been described. [provided by RefSeq, Sep 2018]

Feb 15, 2023

The c.4349C>T (p.S1450L) alteration is located in exon 30 (coding exon 30) of the CDC42BPA gene. This alteration results from a C to T substitution at nucleotide position 4349, causing the serine (S) at amino acid position 1450 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
