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]

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -6 ACMG points.

PP2
Missense variant in gene, where missense usually causes diseases (based on misZ statistic), CDC42BPB. . Gene score misZ 3.6598 (greater than the threshold 3.09). Trascript score misZ 3.9995 (greater than threshold 3.09). GenCC has associacion of gene with Chilton-Okur-Chung neurodevelopmental syndrome, complex neurodevelopmental disorder.
BP4
Computational evidence support a benign effect (MetaRNN=0.10399246).
BS1
Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.0000657 (10/152138) while in subpopulation AFR AF= 0.000241 (10/41414). AF 95% confidence interval is 0.000131. There are 0 homozygotes in gnomad4. There are 4 alleles in male gnomad4 subpopulation. Median coverage is 33. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting
BS2
High AC in GnomAd4 at 10 AD gene.

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 03, 2023The c.5120C>T (p.P1707L) alteration is located in exon 37 (coding exon 37) of the CDC42BPB gene. This alteration results from a C to T substitution at nucleotide position 5120, causing the proline (P) at amino acid position 1707 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
