-Relevance to Autism
Bandi et al., 2026 reported three unrelated individuals with homozygous truncating variants in the UBA7 gene presenting with a neurodevelopmental disorder characterized by developmental delay, intellectual disability, autism, and nonspecific dysmorphic features; truncating variants resulted in loss of catalytic activity, protein stability, and localization, and patient fibroblasts with the p.Lys709SerfsTer45 variant demonstrated reduced UBA7 transcript, production of a truncated and unstable UBA7 protein, and an inability to induce ISGylation upon interferon beta treatment, indicating a dysfunctional ISGylation system. De novo and inherited heterozygous loss-of-function and missense variants have been identified in ASD probands from the Autism Sequencing Consortium, the SPARK cohort, and the mAGRE cohort (Satterstrom et al., 2020; Trost et al., 2022; Cirnigliaro et al., 2023).
Molecular Function
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 E1 ubiquitin-activating enzyme family. The encoded enzyme is a retinoid target that triggers promyelocytic leukemia (PML)/retinoic acid receptor alpha (RARalpha) degradation and apoptosis in acute promyelocytic leukemia, where it is involved in the conjugation of the ubiquitin-like interferon-stimulated gene 15 protein.
