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]

ACMG classification

Verdict is Likely_pathogenic. Variant got 6 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant where missense usually causes diseases, CUL3
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.906
• PP5: Variant 2-224503791-T-C is Pathogenic according to our data. Variant chr2-224503791-T-C is described in ClinVar as [Pathogenic]. Clinvar id is 30323.Status of the report is no_assertion_criteria_provided, 0 stars.
