Genes affected

USP21 (HGNC:12620): (ubiquitin specific peptidase 21) This gene encodes a member of the C19 peptidase family, also known as family 2 of ubiquitin carboxy-terminal hydrolases. The encoded protein cleaves ubiquitin from ubiquitinated proteins for recycling in intracellular protein degradation. The encoded protein is also able to release NEDD8, a ubiquitin-like protein, from NEDD8-conjugated proteins. This gene has been referred to as USP16 and USP23 but is now known as USP21. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Feb 2016]

The c.965G>A (p.R322H) alteration is located in exon 7 (coding exon 5) of the USP21 gene. This alteration results from a G to A substitution at nucleotide position 965, causing the arginine (R) at amino acid position 322 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
