UBE2U

Chr 1

ubiquitin conjugating enzyme E2 U

This ubiquitin-conjugating enzyme catalyzes the covalent attachment of ubiquitin to other proteins and is involved in DNA repair and protein degradation pathways. Mutations cause autosomal recessive intellectual disability with microcephaly and growth retardation. The gene shows minimal constraint against loss-of-function variants, consistent with recessive inheritance where heterozygous carriers are typically unaffected.

This gene has evidence for multiple mechanisms of pathogenicity (gain-of-function and dominant-negative). Both the Badonyi & Marsh prediction and the broader genomic evidence point to gain-of-function as the predominant mechanism. Different variants in this gene may act through different mechanisms — interpret in context of the specific variant.

Note: In-silico variant effect predictors (SIFT, PolyPhen, REVEL, CADD) may underestimate pathogenicity of missense variants in genes with GOF or DN mechanisms. Consider functional evidence and clinical context.
