Relevance to Autism

Several studies have identified rare mutations in the GRIN2B gene in individuals with autism. For example, O'Roak et al. (2011) found a single individual with a 3' splice mutation of GRIN2B, Myers et al. (2011) found an excess of rare non-synonymous mutations in GRIN2B in both autism and schizophrenia and Talkowski et al. (2012) found two CNVs involving GRIN2B in ASD patients. As well, Yoo et al. (2012) showed association of GRIN2B markers in a Korean cohort of 151 families. Studies have also found genetic association of the GRIN2B gene with obsessive-compulsive disorder (Arnold et al., 2004) as well as with schizophrenia (Ohtsuki et al., 2001).

Molecular Function

NMDA receptor subtype of glutamate-gated ion channels with high calcium permeability and voltage-dependent sensitivity to magnesium.

High Confidence

Studies have identified rare mutations in the GRIN2B gene with autism. In particular, O'Roak et al. (2011) found a single individual with a 3' splice mutation of GRIN2B, Myers et al. (2011) found an excess of rare non-synonymous mutations in GRIN2B in both autism and schizophrenia. As well, Yoo et al. (2012) showed association of GRIN2B markers in a Korean cohort of 151 families. Studies have also found genetic association of the GRIN2B gene with obsessive-compulsive disorder (Arnold et al., 2004) as well as with schizophrenia (Ohtsuki et al., 2001). PMID 22495309 and 23160955 reported 3 de novo LoF in GRIN2B. 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 GRIN2B as a gene meeting high statistical significance with a FDR ?0.01, meaning that this gene had a ?99% chance of being a true autism gene (PMID 25363760). 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). Platzer et al., 2017 evaluated 48 novel and 43 previously published individuals with de novo GRIN2B variants; 13 of the 48 novel individuals in this report were reported to have ASD as a phenotype.

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.
