Relevance to Autism

Two de novo loss-of-function variants in the WAC gene have been identified in ASD probands from the Simons Simplex Collection (refs). A third de novo loss-of-function variant in this gene was identified in an ASD proband in Tammimies et al., 2015.

Molecular Function

Acts as a linker between gene transcription and histone H2B monoubiquitination at 'Lys-120' (H2BK120ub1). Interacts with the RNA polymerase II transcriptional machinery via its WW domain and with RNF20-RNF40 via its coiled coil region, thereby linking and regulating H2BK120ub1 and gene transcription. Regulates the cell-cycle checkpoint activation in response to DNA damage. Positive regulator of amino acid starvation-induced autophagy. May negatively regulate the ubiquitin proteasome pathway.

Strong Candidate, Syndromic

Two de novo LoF variants in the WAC gene (both frameshift) were identified in ASD probands from the Simons Simplex Collection (PMID 25363768). A third de novo LoF variant in the WAC gene was recently identified in an ASD proband in PMID 26325558. 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). PMID 26264232 identified de novo LoF variants in WAC in patients with developmental delay. PMID 26757981 reported additional ID cases with de novo, potentially gene disruptive WAC variants; two of these cases also presented with autism. Clinical evalution of patients from PMIDs 26264232 and 26757981 revealed phenotypic overlap consisting of developmental delay/intellectual disability, hypotonia, behavioral problems, and distinctive facial dysmorphism, possibly defining a novel form of syndromic intellectual disability. Similar clinical features have been reported in individuals with 10p12-p11 microdeletion syndrome, for which the shortest deleted region contains the WAC gene (Wentzel et al., 2011; Okamoto et al., 2012).

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.

The syndromic category includes mutations that are associated with a substantial degree of increased risk and consistently linked to additional characteristics not required for an ASD diagnosis. If there is independent evidence implicating a gene in idiopathic ASD, it will be listed as "#S" (e.g., 2S, 3S, etc.). If there is no such independent evidence, the gene will be listed simply as "S."
