Genes affected

UBE2J2 (HGNC:19268): (ubiquitin conjugating enzyme E2 J2) The modification of proteins with ubiquitin is an important cellular mechanism for targeting abnormal or short-lived proteins for degradation. Ubiquitination involves at least three classes of enzymes: ubiquitin-activating enzymes, or E1s, ubiquitin-conjugating enzymes, or E2s, and ubiquitin-protein ligases, or E3s. This gene encodes a member of the E2 ubiquitin-conjugating enzyme family. This enzyme is located in the membrane of the endoplasmic reticulum. Multiple alternatively spliced transcript variants have been found for this gene, but the full-length nature of some variants has not been defined. [provided by RefSeq, Jul 2008]

Collection Method: clinical testing

The c.64C>G (p.L22V) alteration is located in exon 2 (coding exon 1) of the UBE2J2 gene. This alteration results from a C to G substitution at nucleotide position 64, causing the leucine (L) at amino acid position 22 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
