Relevance to Autism

MBD5 was originally identified as a candidate gene in a report describing copy number variation in patients with unexplained mental retardation (Wagenstaller et al., 2007). Since that report, numerous studies have implicated MBD5 haploinsufficiency as being associated with intellectual disability, epilepsy, and autism spectrum disorder (Jaillard et al., 2009; van Bon et al., 2010; Williams et al., 2010; Talkowski et al., 2011). More recently, a balanced chromosomal abnormality (BCA) leading to MBD5 disruption was identified in an ASD case (Talkowski et al., 2012).

Molecular Function

This gene encodes a member of the methyl-CpG-binding domain (MBD) family. Mutations in this gene cause mental retardation autosomal dominant type 1. Haploinsufficiency of this gene is associated with a syndrome involving microcephaly, intellectual disabilities, severe speech impairment, and seizures.

MBD5 was originally identified as a candidate gene in a report describing copy number variation in patients with unexplained mental retardation (Wagenstaller et al., 2007). Since that report, numerous studies have implicated MBD5 haploinsufficiency as being associated with intellectual disability, epilepsy, and autism spectrum disorder (Jaillard et al., 2009; van Bon et al., 2010; Williams et al., 2010; Talkowski et al., 2011). In particular, Talkowski et al. (2011) showed that the MBD5 locus defines the critical region of 2q23.1 microdeletion syndrome and showed significant reduction in MBD5 RNA expression in lymphoblastoid cell lines of individuals with MBD5 deletions. That report also showed association of a missense variant (Gly79Glu) in 6/747 ASD cases compared to 3/3042 controls (P=0.012). More recently, a balanced chromosomal abnormality (BCA) leading to MBD5 disruption was identified in an ASD case (Talkowski et al., 2012).

High Confidence

See all Category 1 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."

Since that report, numerous studies have implicated MBD5 haploinsufficiency as being associated with intellectual disability, epilepsy, and autism spectrum disorder (Jaillard et al., 2009; van Bon et al., 2010; Williams et al., 2010; Talkowski et al., 2011). In particular, Talkowski et al. (2011) showed that the MBD5 locus defines the critical region of 2q23.1 microdeletion syndrome and showed significant reduction in MBD5 RNA expression in lymphoblastoid cell lines of individuals with MBD5 deletions. That report also showed association of a missense variant (Gly79Glu) in 6/747 ASD cases compared to 3/3042 controls (P=0.012). More recently, a balanced chromosomal abnormality (BCA) leading to MBD5 disruption was identified in an ASD case (Talkowski et al., 2012).

MBD5 was originally identified as a candidate gene in a report describing copy number variation in patients with unexplained mental retardation (Wagenstaller et al., 2007). Since that report, numerous studies have implicated MBD5 haploinsufficiency as being associated with intellectual disability, epilepsy, and autism spectrum disorder (Jaillard et al., 2009; van Bon et al., 2010; Williams et al., 2010; Talkowski et al., 2011).

Krishnan Probability Score

Score 0.47931065467408

Ranking 8164/25841 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 0.99985233325303

Ranking 740/18225 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
Iossifov Probability Score

Score 0.968

Ranking 62/239 scored genes


[Show Scoring Methodology]
Supplementary dataset S2 in the paper by Iossifov et al. (PNAS 112, E5600-E5607 (2015)) lists 239 genes with a probability of at least 0.8 of being associated with autism risk (column I). This probability metric combines the evidence from de novo likely-gene- disrupting and missense mutations and assesses it against the background mutation rate in unaffected individuals from the University of Washington’s Exome Variant Sequence database (evs.gs.washington.edu/EVS/). The list of probability scores can be found here: www.pnas.org/lookup/suppl/doi:10.1073/pnas.1516376112/- /DCSupplemental/pnas.1516376112.sd02.xlsx
Sanders TADA Score

Score 0.094211824712552

Ranking 63/18665 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 50

Ranking 32/461 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 0.56568536340851

Ranking 190/20870 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.
