Genes affected

USP8 (HGNC:12631): (ubiquitin specific peptidase 8) This gene encodes a protein that belongs to the ubiquitin-specific processing protease family of proteins. The encoded protein is thought to regulate the morphology of the endosome by ubiquitination of proteins on this organelle and is involved in cargo sorting and membrane trafficking at the early endosome stage. This protein is required for the cell to enter the S phase of the cell cycle and also functions as a positive regulator in the Hedgehog signaling pathway in development. Pseudogenes of this gene are present on chromosomes 2 and 6. Alternate splicing results in multiple transcript variants. [provided by RefSeq, Sep 2013]

USP50 (HGNC:20079): (ubiquitin specific peptidase 50) Enables ubiquitin-like protein-specific protease activity. Acts upstream of or within several processes, including nuclear speck organization; positive regulation of NLRP3 inflammasome complex assembly; and positive regulation of macromolecule metabolic process. Predicted to be active in several cellular components, including dendritic spine; midbody; and postsynaptic density. Predicted to be extrinsic component of endosome membrane and extrinsic component of plasma membrane. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.72).
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.136 is higher than 0.05.
