Relevance to Autism

De novo variants (six multigenic deletions, one nonsense variant) affecting the USP7 gene were identified in seven patients presenting with developmental delay/intellectual disability, with five of these cases having an additional diagnosis of ASD (Hao et al., 2015). Subsequent statistical analysis determined that there was a strong correlation between the seven patients having both a de novo USP7 variant and the expressed phenotype that was likely not due to chance (p<0.0001).

Molecular Function

Hydrolase that deubiquitinates target proteins such as FOXO4, p53/TP53, MDM2, ERCC6, DNMT1, UHRF1, PTEN and DAXX. Together with DAXX, prevents MDM2 self-ubiquitination and enhances the E3 ligase activity of MDM2 towards p53/TP53, thereby promoting p53/TP53 ubiquitination and proteasomal degradation. Deubiquitinates p53/TP53 and MDM2 and strongly stabilizes p53/TP53 even in the presence of excess MDM2, and also induces p53/TP53-dependent cell growth repression and apoptosis. In association with DAXX, is involved in the deubiquitination and translocation of PTEN from the nucleus to the cytoplasm. Involved in cell proliferation during early embryonic development.

Strong Candidate

De novo variants (six multigenic deletions, one nonsense variant) affecting the USP7 gene were identified in seven patients presenting with developmental delay/intellectual disability, with five of these cases having an additional diagnosis of ASD (Hao et al., 2015). Subsequent statistical analysis determined that there was a strong correlation between the seven patients having both a de novo USP7 variant and the expressed phenotype that was likely not due to chance (p<0.0001). This gene was identified in Iossifov et al. 2015 as a strong candidate to be an ASD risk gene based on a combination of de novo mutational evidence and the absence or very low frequency of mutations in controls (PMID 26401017).

Strong Candidate

See all Category 2 Genes

We considered a rigorous statistical comparison between cases and controls, yielding genome-wide statistical significance, with independent replication, to be the strongest possible evidence for a gene. These criteria were relaxed slightly for category 2.
