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]

The c.5105G>A (p.R1702Q) alteration is located in exon 36 (coding exon 36) of the CDC42BPA gene. This alteration results from a G to A substitution at nucleotide position 5105, causing the arginine (R) at amino acid position 1702 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
