Studies have found genetic association and rare variations in the UBE3A gene that are associated with autism. Association was found in families of the Collaborative Linkage Study of Autism (Nurmi et al., 2001), and rare variants were found in cases of European ancestry.
Molecular Function
This gene encodes an E3 ubiquitin-protein ligase, part of the ubiquitin protein degradation system. This imprinted gene is maternally expressed in brain and biallelically expressed in other tissues.

Linkage disequilibrium at the Angelman syndrome gene UBE3A in autism families.
A novel UBE3A sequence variant identified in eight related individuals with neurodevelopmental delay, results in a phenotype which does not match the clinical criteria of Angelman syndrome
Dube3a null mutants display abnormal locomotive behavior and circadian rhythms, and defective long-term memory. Flies that overexpress Ube3a in the nervous system also display locomotion defects, dependent on the ubiquitin ligase activity. Missense mutations in UBE3A alleles of Angelman syndrome patients alter amino acid residues conserved in the fly protein, and when introduced into dube3a, behave as loss-of-function mutations. Loss of function of Ube3a leads to climbing defects and overexpression causes changes in synaptic transmission in the neuromuscular junction. Ube3a mutants also show reduced gene and protein expression of Ube3a, an effect more pronounced in mutants with paternally inherited null mutation. Knockout and knockdown mutants show learning deficits which can be rescued by reexpression of genomic or human variant of Ube3a. The learning deficits are not due to locomotor activity ot taste sensitivity impairments as those are not affected in mutants.
