Genes affected

UBE2N (HGNC:12492): (ubiquitin conjugating enzyme E2 N) 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. Studies in mouse suggest that this protein plays a role in DNA postreplication repair. [provided by RefSeq, Jul 2008]

The c.347A>G (p.N116S) alteration is located in exon 3 (coding exon 3) of the UBE2N gene. This alteration results from a A to G substitution at nucleotide position 347, causing the asparagine (N) at amino acid position 116 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
