Relevance to Autism

This gene was identified in an ASD whole-exome sequencing study and subsequent TADA (transmission and de novo association) analysis as a gene strongly enriched for variants likely to affect ASD risk with a false discovery rate (FDR) of <0.1 (De Rubeis et al., 2014).

Molecular Function

Histone methyltransferase that methylates 'Lys-4' of histone H3; H3 'Lys-4' methylation represents a specific tag for epigenetic transcriptional activation. Central component of the MLL2/3 complex, a coactivator complex of nuclear receptors, involved in transcriptional coactivation. KMT2C/MLL3 may be a catalytic subunit of this complex.

Description

A de novo LoF variant in the KMT2C gene was identified in an ASD proband from the Simon Simplex Collection (PMIDs 22495309), while a second de novo LoF variant in this gene was identified in one ASD proband from 2,270 trios screened by the Autism Sequencing Consortium (PMID 25363760). Analysis of rare coding variation in 3,871 ASD cases and 9,937 ancestry-matched or paternal controls from the Autism Sequencing Consortium (ASC) identified KMT2C as a gene meeting high statistical significance with a 0.01 < FDR 0.05, meaning that this gene had a 95% chance of being a true autism gene (PMID 25363760). Additional de novo probably damaging missense variants in KMT2C were identified in ASD probands from the Simons Simplex Collection (Iossifov et al., 2014; Krumm et al., 2015). A de novo LoF variant in KMT2C was identifed in a proband from the Pediatric Cardiac Genetics Consortium who presented with ASD, developmental delay, and intellectual disability in addition to congenital heart disease (Homsy et al., 2015). Koemans et al., 2017 identified four patients with intellectual disability, language delay, and motor delay that carried de novo LoF variants in the KMT2C gene; two of these patients presented with autism, one patient presented with PDD-NOS, and one presented with autistic traits.

Description

A de novo LoF variant in the KMT2C gene was identified in an ASD proband from the Simon Simplex Collection (PMIDs 22495309), while a second de novo LoF variant in this gene was identified in one ASD proband from 2,270 trios screened by the Autism Sequencing Consortium (PMID 25363760). Analysis of rare coding variation in 3,871 ASD cases and 9,937 ancestry-matched or paternal controls from the Autism Sequencing Consortium (ASC) identified KMT2C as a gene meeting high statistical significance with a 0.01 < FDR 0.05, meaning that this gene had a 95% chance of being a true autism gene (PMID 25363760). Additional de novo probably damaging missense variants in KMT2C were identified in ASD probands from the Simons Simplex Collection (Iossifov et al., 2014; Krumm et al., 2015). A de novo LoF variant in KMT2C was identifed in a proband from the Pediatric Cardiac Genetics Consortium who presented with ASD, developmental delay, and intellectual disability in addition to congenital heart disease (Homsy et al., 2015). Koemans et al., 2017 identified four patients with intellectual disability, language delay, and motor delay that carried de novo LoF variants in the KMT2C gene; two of these patients presented with autism, one patient presented with PDD-NOS, and one presented with autistic traits.

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).

ExAC Score

Score 1

Ranking 16/18225 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

[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

Ranking 17/18665 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).
