Genes affected

UBE2R2 (HGNC:19907): (ubiquitin conjugating enzyme E2 R2) Protein kinase CK2 is a ubiquitous and pleiotropic Ser/Thr protein kinase involved in cell growth and transformation. This gene encodes a protein similar to the E2 ubiquitin conjugating enzyme UBC3/CDC34. Studies suggest that CK2-dependent phosphorylation of this ubiquitin-conjugating enzyme functions by regulating beta-TrCP substrate recognition and induces its interaction with beta-TrCP, enhancing beta-catenin degradation.

ACMG classification

Verdict is Uncertain_significance. Variant got 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.07816896).

The c.574A>G (p.I192V) alteration is located in exon 5 (coding exon 5) of the UBE2R2 gene. This alteration results from a A to G substitution at nucleotide position 574, causing the isoleucine (I) at amino acid position 192 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
