Genes affected

USP35 (HGNC:20061): (ubiquitin specific peptidase 35) This gene encodes a member of the peptidase C19 family of ubiquitin-specific proteases. These deubiquitinating enzymes (DUBs) catalyze the removal of ubiquitin proteins from other proteins. The encoded protein associates with polarized mitochondria and has been shown to inhibit NF-kappa B activation and delay PARK2-mediated degradation of mitochondria. Expression of this gene is upregulated by the let-7a microRNA and reduced expression has been observed in human tumor tissues. [provided by RefSeq, Jul 2017]

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=0.17730221).

The c.770G>C (p.S257T) alteration is located in exon 3 (coding exon 2) of the USP35 gene. This alteration results from a G to C substitution at nucleotide position 770, causing the serine (S) at amino acid position 257 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
