Genes affected

CUL2 (HGNC:2552): (cullin 2) Enables ubiquitin protein ligase binding activity. Predicted to be involved in SCF-dependent proteasomal ubiquitin-dependent protein catabolic process and protein ubiquitination. Predicted to act upstream of or within protein catabolic process. Located in nucleoplasm. Part of Cul2-RING ubiquitin ligase complex. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Our verdict: Uncertain_significance. The variant received 1 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.29566061).

Collection Method: clinical testing

The c.1582A>G (p.I528V) alteration is located in exon 15 (coding exon 15) of the CUL2 gene. This alteration results from a A to G substitution at nucleotide position 1582, causing the isoleucine (I) at amino acid position 528 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
