Genes affected

USP46 (HGNC:20075): (ubiquitin specific peptidase 46) Modification of cellular proteins by ubiquitin is an essential regulatory mechanism controlled by the coordinated action of multiple ubiquitin-conjugating and deubiquitinating enzymes. USP46 belongs to a large family of cysteine proteases that function as deubiquitinating enzymes (Quesada et al., 2004 [PubMed 14715245]).[supplied by OMIM, Jun 2009]

ACMG classification

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

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.99).
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.328 is higher than 0.05.
