Genes affected

JOSD2 (HGNC:28853): (Josephin domain containing 2) This gene encodes a protein containing a Josephin domain. Josephin domain-containing proteins are deubiquitinating enzymes which catalyze the hydrolysis of the bond between the C-terminal glycine of the ubiquitin peptide and protein substrates. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. [provided by RefSeq, Jul 2012]

The c.368G>A (p.R123Q) alteration is located in exon 4 (coding exon 3) of the JOSD2 gene. This alteration results from a G to A substitution at nucleotide position 368, causing the arginine (R) at amino acid position 123 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
