Genes affected

USP36 (HGNC:20062): (ubiquitin specific peptidase 36) This gene encodes a member of the peptidase C19 or ubiquitin-specific protease family of cysteine proteases. Members of this family remove ubiquitin molecules from polyubiquitinated proteins. The encoded protein may deubiquitinate and stabilize the transcription factor c-Myc, also known as MYC, an important oncoprotein known to be upregulated in most human cancers. The encoded protease may also regulate the activation of autophagy. This gene exhibits elevated expression in some breast and lung cancers. [provided by RefSeq, Mar 2016]

ACMG classification

Verdict is Uncertain_significance. Variant got 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.20278537).

Ambry Genetics

Oct 17, 2023

The c.2764G>T (p.G922C) alteration is located in exon 16 (coding exon 14) of the USP36 gene. This alteration results from a G to T substitution at nucleotide position 2764, causing the glycine (G) at amino acid position 922 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
