Genes affected

USP3 (HGNC:12626): (ubiquitin specific peptidase 3) Enables histone binding activity and thiol-dependent deubiquitinase. Involved in several processes, including DNA repair; histone deubiquitination; and regulation of protein stability. Located in several cellular components, including Flemming body; cytoplasmic ribonucleoprotein granule; and nucleoplasm. [provided by Alliance of Genome Resources, Apr 2022]

USP3-AS1 (HGNC:44140): (USP3 antisense RNA 1)

ACMG classification

Our verdict: Uncertain_significance. The variant received 4 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.865
