Genes affected

USP4 (HGNC:12627): (ubiquitin specific peptidase 4) The protein encoded by this gene is a protease that deubiquitinates target proteins such as ADORA2A and TRIM21. The encoded protein shuttles between the nucleus and cytoplasm and is involved in maintaining operational fidelity in the endoplasmic reticulum. Three transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Oct 2011]

The c.2381A>G (p.H794R) alteration is located in exon 18 (coding exon 18) of the USP4 gene. This alteration results from a A to G substitution at nucleotide position 2381, causing the histidine (H) at amino acid position 794 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
