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]

The c.2161G>T (p.V721F) alteration is located in exon 12 (coding exon 11) of the OTUD7B gene. This alteration results from a G to T substitution at nucleotide position 2161, causing the valine (V) at amino acid position 721 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
