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]

ACMG classification

Classification was made for transcript

Our verdict: Likely_pathogenic. The variant received 9 ACMG points.

PM2

Very rare variant in population databases, with high coverage;

PP2

Missense variant in the gene, where a lot of missense mutations are associated with disease in ClinVar. The gene has 3 curated pathogenic missense variants (we use a threshold of 10). The gene has 0 curated benign missense variants. Gene score misZ: 2.6072 (below the threshold of 3.09). Trascript score misZ: 3.5151 (above the threshold of 3.09). GenCC associations: The gene is linked to ACCES syndrome, multiple congenital anomalies/dysmorphic syndrome.

PP3

MetaRNN computational evidence supports a deleterious effect, 0.983

PP5

Variant 19-34428503-G-T is Pathogenic according to our data. Variant chr19-34428503-G-T is described in ClinVar as [Likely_pathogenic]. Clinvar id is 979175.Status of the report is criteria_provided_single_submitter, 1 stars.
