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

Classification made for transcript

Verdict is Uncertain_significance. Variant got 3 ACMG points.

PM2

Very rare variant in population databases, with high coverage;

PP2

Missense variant where missense usually causes diseases, USP46

PP3

Multiple lines of computational evidence support a deleterious effect 7: AlphaMissense, Cadd, Dann, Eigen, FATHMM_MKL, phyloP100way_vertebrate, PrimateAI [when BayesDel_addAF, max_spliceai, M_CAP, MetaRNN, MutationTaster was below the threshold]

BP4

Computational evidence support a benign effect (MetaRNN=0.3592301).

Ambry Genetics

Nov 12, 2021

The c.242C>T (p.A81V) alteration is located in exon 3 (coding exon 3) of the USP46 gene. This alteration results from a C to T substitution at nucleotide position 242, causing the alanine (A) at amino acid position 81 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
