Relevance to Autism

A de novo frameshift variant in the UBR5 gene has been identified in an ASD proband from the Simons Simplex Collection (PMID 25961944). A missense mutation in the UBR5 gene was detected in all affected individuals of a Japanese pedigree (6 affected individuals through 4 generations) with familial adult myoclonic epilepsy, but not in any non-affected family members; this variant was also not detected in 85 unrelated healthy residents of the pedigree's community, nor in 24 control individuals of various ethnicities (Kato et al., 2012).

Molecular Function

This gene encodes a progestin-induced protein, which belongs to the HECT (homology to E6-AP carboxyl terminus) family. The HECT family proteins function as E3 ubiquitin-protein ligases, targeting specific proteins for ubiquitin-mediated proteolysis. This gene potentially has a role in regulation of cell proliferation or differentiation.
