The NM_003590.5(CUL3):c.1849C>G (p.Gln617Glu) variant causes a missense change involving the alteration of a conserved nucleotide. The gene CUL3 is a tumor suppressor gene (CancerMine: 3 TSG, 2 driver citations). The gene CUL3 is a cancer driver gene (CancerMine: 3 TSG, 2 driver citations). The variant allele was found at a cumulative frequency of 0.0000131 (AC=2) in the gnomAD database across 152,128 control chromosomes (no homozygotes observed). The grpmax filtering allele frequency (95% CI) is 0.00000488. Splicing prediction tools (SpliceAI) predict no significant impact on normal splicing. The affected nucleotide is highly conserved across species (PhyloP 100-way vertebrate score: 10.00). Variant has been reported in ClinVar as Uncertain Significance (★★). Other variants at the same amino acid position have been reported in ClinVar (not pathogenic): p.Q617= (synonymous): Likely_benign (ClinVar VariationId 2874676, 1 star) This exact variant is curated in the UniProt human variants database as Uncertain Significance; it is also listed as a COSMIC curated somatic variant.

Genes affected

CUL3 (HGNC:2553): (cullin 3) This gene encodes a member of the cullin protein family. The encoded protein plays a critical role in the polyubiquitination and subsequent degradation of specific protein substrates as the core component and scaffold protein of an E3 ubiquitin ligase complex. Complexes including the encoded protein may also play a role in late endosome maturation. Mutations in this gene are a cause of type 2E pseudohypoaldosteronism. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. [provided by RefSeq, Mar 2012]
