Genes affected

USP48 (HGNC:18533): (ubiquitin specific peptidase 48) This gene encodes a protein containing domains that associate it with the peptidase family C19, also known as family 2 of ubiquitin carboxyl-terminal hydrolases. Family members function as deubiquitinating enzymes, recognizing and hydrolyzing the peptide bond at the C-terminal glycine of ubiquitin. Enzymes in peptidase family C19 are involved in the processing of poly-ubiquitin precursors as well as that of ubiquitinated proteins. Alternate transcriptional splice variants, encoding different isoforms, have been characterized. [provided by RefSeq, Jul 2008]

The c.1900T>A (p.S634T) alteration is located in exon 15 (coding exon 15) of the USP48 gene. This alteration results from a T to A substitution at nucleotide position 1900, causing the serine (S) at amino acid position 634 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
