Genes affected

OTUD7B (HGNC:16683): (OTU deubiquitinase 7B) Enables Lys48-specific deubiquitinase activity and thiol-dependent deubiquitinase. Involved in several processes, including negative regulation of I-kappaB kinase/NF-kappaB signaling; negative regulation of macromolecule metabolic process; and protein deubiquitination. Located in cytoplasm and nucleus. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Verdict is Uncertain_significance. Variant got 1 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.3203761).

The c.2424C>A (p.S808R) alteration is located in exon 12 (coding exon 11) of the OTUD7B gene. This alteration results from a C to A substitution at nucleotide position 2424, causing the serine (S) at amino acid position 808 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
