DD/NDD, ASDRelevance 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.

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.
