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]

Uncertain significance, criteria provided, single submitter	clinical testing	Invitae	Aug 06, 2020	This sequence change replaces glutamine with histidine at codon 116 of the CUL4B protein (p.Gln116His). The glutamine residue is moderately conserved and there is a small physicochemical difference between glutamine and histidine. This variant is present as hemizygous in an individual in the population databases (rs755306871, ExAC 0.01%) but has not been reported in the literature in individuals with a CUL4B-related disease. In summary, this variant is a rare missense change that is not predicted to affect protein function. There is no indication that it causes disease, but the available evidence is currently insufficient to prove that conclusively. Therefore, it has been classified as a Variant of Uncertain Significance. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated, but these predictions have not been confirmed by published functional studies. -
