Comment on list classification: New gene added by Zornitza Stark. Sufficient evidence to rate this gene Green at the next GMS panel update - PMID:33420346 report 4 unrelated families with different homozygous LoF variants in UBE4A, supported by some functional data and animal model. Severe ID and GDD was a feature in all affected individuals (8 total).

UBE4A is not associated with any phenotype in OMIM (last edited on 17/09/2010) but has a 'probable' disease confidence rating for 'UBE4A-associated neurodevelopmental disorder' in Gene2Phenotype.

Green List (high evidence)

8 individuals, from 4 unrelated families, with syndromic intellectual disability and global developmental delay (other clinical features included hypotonia, short stature, seizures, and behaviour disorder. Exome sequencing identified biallelic loss-of-function variants in UBE4A in the 4 families, with variants segregating with disease and parents carriers. They demonstrated that UBE4A loss-of-function variants reduced RNA expression and protein levels in clinical samples. Mice generated to mimic patient-specific Ube4a loss-of-function variant exhibited muscular and neurological/behavioural abnormalities, some of which are suggestive of the clinical abnormalities seen in the affected individuals.
