Genes affected
CDC42BPB (HGNC:1738): (CDC42 binding protein kinase beta) This gene encodes a member of the serine/threonine protein kinase family. The encoded protein contains a Cdc42/Rac-binding p21 binding domain resembling that of PAK kinase. The kinase domain of this protein is most closely related to that of myotonic dystrophy kinase-related ROK. Studies of the similar gene in rat suggested that this kinase may act as a downstream effector of Cdc42 in cytoskeletal reorganization. [provided by RefSeq, Jul 2008]

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 22, 2023The c.4895C>T (p.P1632L) alteration is located in exon 35 (coding exon 35) of the CDC42BPB gene. This alteration results from a C to T substitution at nucleotide position 4895, causing the proline (P) at amino acid position 1632 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
