Genes affected

CUL4B (HGNC:2555): (cullin 4B) This gene is a member of the cullin family. The encoded protein forms a complex that functions as an E3 ubiquitin ligase and catalyzes the polyubiquitination of specific protein substrates in the cell. The protein interacts with a ring finger protein, and is required for the proteolysis of several regulators of DNA replication including chromatin licensing and DNA replication factor 1 and cyclin E. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

ACMG classification

Classification made for transcript

Verdict is Benign. Variant got -8 ACMG points.

PP2

Missense variant where missense usually causes diseases, CUL4B

BP4

Computational evidence support a benign effect (MetaRNN=0.03133288).

BS1

Variant frequency is greater than expected in population sas. gnomad4_exome allele frequency = 0.0000156 (17/1091398) while in subpopulation SAS AF= 0.000259 (14/53987). AF 95% confidence interval is 0.000156. There are 0 homozygotes in gnomad4_exome. There are 6 alleles in male gnomad4_exome subpopulation. Median coverage is 27. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting
