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]

The c.423_431delCTCCTCCTC variant in the XXX gene has not been reported previously as a pathogenic variant, nor as a benign variant, to our knowledge. The c.423_431delCTCCTCCTC variant causes an inframe deletion of three amino acids starting at Serine 144, denoted p.S144_S146del. The c.423_431delCTCCTCCTC variant is observed in 5/86720 (0.0058%) alleles from individuals of non-Finnish European background, and 5/190079 total alleles in large population cohorts (Lek et al., 2016). We interpret c.423_431delCTCCTCCTC as a likely pathogenic variant. -

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. This variant, c.423_431del, results in the deletion of 3 amino acid(s) of the CUL4B protein (p.Ser144_Ser146del), but otherwise preserves the integrity of the reading frame. This variant is present in population databases (rs756411375, ExAC 0.004%), including at least one homozygous and/or hemizygous individual. This variant has not been reported in the literature in individuals with CUL4B-related conditions. ClinVar contains an entry for this variant (Variation ID:¬†504176). Experimental studies and prediction algorithms are not available for this variant, and the functional significance of the affected amino acid(s) is currently unknown. -

PreventionGenetics, part of Exact Sciences

Significance: Uncertain significance

Review Status: no assertion criteria provided

Collection Method: clinical testing

The CUL4B c.423_431del9 variant is predicted to result in an in-frame deletion (p.Ser144_Ser146del). To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.0057% of alleles in individuals of European (Non-Finnish) descent in gnomAD. At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
