Genes affected

USP15 (HGNC:12613): (ubiquitin specific peptidase 15) This gene encodes a member of the ubiquitin specific protease (USP) family of deubiquitinating enzymes. USP enzymes play critical roles in ubiquitin-dependent processes through polyubiquitin chain disassembly and hydrolysis of ubiquitin-substrate bonds. The encoded protein associates with the COP9 signalosome, and also plays a role in transforming growth factor beta signalling through deubiquitination of receptor-activated SMAD transcription factors. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene, and a pseudogene of this gene is located on the long arm of chromosome 2.

The c.1405A>C (p.K469Q) alteration is located in exon 11 (coding exon 11) of the USP15 gene. This alteration results from a A to C substitution at nucleotide position 1405, causing the lysine (K) at amino acid position 469 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
