Relevance to Autism

Missense variants in the ZBTB20 gene were identified in eight patients with Primrose syndrome (MIM 259050), a condition characterized by increased growth of the brain and body height, intellectual disability, autism, and other behavioral concerns. Four of the Primrose syndrome patients that were identified with ZBTB20 missense variants also presented with autism (Cordeddu et al., 2014). ZBTB20 lies within the minimum region of overlap for 3q13.31 (del3q13.31) microdeletion syndrome (MIM 615433), a multisystem disorder characterized by increased postnatal growth, hypotonia, intellectual disability, disturbed behavior, and unusual facial features, as well as autism in some cases (Molin et al., 2012; Shuvarikov et al., 2013).

Molecular Function

May be a transcription factor that may be involved in hematopoiesis, oncogenesis, and immune responses. ZBTB20 has been shown to act as a cell-fate determinant for CA1 pyramidal neurons in the hippocampus (Xie et al., 2010; Ren et al., 2012).

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.

See all Category S Genes

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."

Description

Missense variants in the ZBTB20 gene were recently identified in eight patients diagnosed with Primrose syndrome; seven of these variants were de novo in origin, and six of these variants were experimentally shown to have functional effects (i.e. reduced promoter binding and impaired function in repressing reporter expression) in a dominant-negative manner. These missense variants were not observed in public or in-house databases. Two of the patients diagnosed with Primrose syndrome that carried de novo functional missense variants were reported in the supplementary material as also presenting with autism (PMID 25017102). ZBTB20 also resides within the critical region for 3q13.31 deletion syndrome, a multisystem disorder marked by intellectual disability, disturbed behavior, and other features (PMID 22180640, PMID 23878096).

Missense variants in the ZBTB20 gene were recently identified in eight patients diagnosed with Primrose syndrome; seven of these variants were de novo in origin, and six of these variants were experimentally shown to have functional effects (i.e. reduced promoter binding and impaired function in repressing reporter expression) in a dominant-negative manner. These missense variants were not observed in public or in-house databases. Two of the patients diagnosed with Primrose syndrome that carried de novo functional missense variants were reported in the supplementary material as also presenting with autism (PMID 25017102). ZBTB20 also resides within the critical region for 3q13.31 deletion syndrome, a multisystem disorder marked by intellectual disability, disturbed behavior, and other features (PMID 22180640, PMID 23878096).

Krishnan Probability Score

Score 0.50313475751475

Ranking 1955/25841 scored genes


[Show Scoring Methodology]
Krishnan and colleagues generated probability scores genome-wide by using a machine learning approach on a human brain-specific gene network. The method was first presented in Nat Neurosci 19, 1454-1462 (2016), and scores for more than 25,000 RefSeq genes can be accessed in column G of supplementary table 3 (see: http://www.nature.com/neuro/journal/v19/n11/extref/nn.4353-S5.xlsx). A searchable browser, with the ability to view networks of associated ASD risk genes, can be found at asd.princeton.edu.

ExAC Score

Score 0.98255723040765

Ranking 2062/18225 scored genes


[Show Scoring Methodology]
The Exome Aggregation Consortium (ExAC) is a summary database of 60,706 exomes that has been widely used to estimate 'constraint' on mutation for individual genes. It was introduced by Lek et al. Nature 536, 285-291 (2016), and the ExAC browser can be found at exac.broadinstitute.org. The pLI score was developed as measure of intolerance to loss-of- function mutation. A pLI > 0.9 is generally viewed as highly constrained, and thus any loss-of- function mutations in autism in such a gene would be more likely to confer risk. For a full list of pLI scores see: ftp://ftp.broadinstitute.org/pub/ExAC_release/release0.3.1/functional_gene_constraint/fordist_cle aned_exac_nonTCGA_z_pli_rec_null_data.txt

Sanders TADA Score

Score 0.94867928396869

Ranking 17782/18665 scored genes


[Show Scoring Methodology]
The TADA score ('Transmission and De novo Association') was introduced by He et al. PLoS Genet 9(8):e1003671 (2013), and is a statistic that integrates evidence from both de novo and transmitted mutations. It forms the basis for the claim of 65 individual genes being strongly associated with autism risk at a false discovery rate of 0.1 (Sanders et al. Neuron 87, 1215-1233 (2015)). The calculated TADA score for 18,665 RefSeq genes can be found in column P of Supplementary Table 6 in the Sanders et al. paper (the column headed 'tadaFdrAscSscExomeSscAgpSmallDel'), which represents a combined analysis of exome data and small de novo deletions (see www.cell.com/cms/attachment/2038545319/2052606711/mmc7.xlsx).

Larsen Cumulative Evidence Score

Score 33

Ranking 67/461 scored genes


[Show Scoring Methodology]
Larsen and colleagues generated gene scores based on the sum of evidence for all available ASD-associated variants in a gene, with assessments based on mode of inheritance, effect size, and variant frequency in the general population. The approach was first presented in Mol Autism 7:44 (2016), and scores for 461 genes can be found in column I in supplementary table 4 from that paper.

Zhang D Score

Score 0.16946517259417

Ranking 4821/20870 scored genes


[Show Scoring Methodology]
The DAMAGES score (disease-associated mutation analysis using gene expression signatures), or D score, was developed to combine evidence from de novo loss-of- function mutation with evidence from cell-type- specific gene expression in the mouse brain (specifically translational profiles of 24 specific mouse CNS cell types isolated from 6 different brain regions). Genes with positive D scores are more likely to be associated with autism risk, with higher-confidence genes having higher D scores. This statistic was first presented by Zhang & Shen (Hum Mutat 38, 204- 215 (2017), and D scores for more than 20,000 RefSeq genes can be found in column M in supplementary table 2 from that paper.
