Genes affected

UBA2 (HGNC:30661): (ubiquitin like modifier activating enzyme 2) Posttranslational modification of proteins by the addition of the small protein SUMO (see SUMO1; MIM 601912), or sumoylation, regulates protein structure and intracellular localization. SAE1 (MIM 613294) and UBA2 form a heterodimer that functions as a SUMO-activating enzyme for the sumoylation of proteins (Okuma et al., 1999 [PubMed 9920803]).[supplied by OMIM, Mar 2010]

Ambry Genetics

Dec 20, 2022

The c.40G>A (p.A14T) alteration is located in exon 1 (coding exon 1) of the UBA2 gene. This alteration results from a G to A substitution at nucleotide position 40, causing the alanine (A) at amino acid position 14 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
