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]

Likely pathogenic, criteria provided, single submitter | clinical testing | Ambry Genetics | Apr 03, 2023 | The c.52_58delGGCCGGG (p.G18Cfs*27) alteration, located in exon 1 (coding exon 1) of the UBA2 gene, consists of a deletion of 7 nucleotides from position 52 to 58, causing a translational frameshift with a predicted alternate stop codon after 27 amino acids. The predicted stop codon occurs in the 5' end of the UBA2 gene. Premature termination codons in the 5’ end of a gene have been reported to escape nonsense-mediated mRNA decay and/or lead to re-initiation (Rivas, 2015; Lindeboom, 2016; Rhee, 2017). Direct evidence for this alteration is unavailable; however, premature termination codons are typically deleterious in nature. This variant was not reported in population-based cohorts in the Genome Aggregation Database (gnomAD). Based on the available evidence, this alteration is classified as likely pathogenic. - |
