-Relevance to Autism
A de novo in-frame deletion variant in the GRM5 gene was identified by exome sequencing in an ASD case from the Simons Simplex Collection (Iossifov et al., 2012). Twelve rare variants in the GRM5 gene were identified in a cohort of 290 non-syndromic ASD cases that were not observed in 300 ethnically matched controls in a subsequent study (Kelleher III et al., 2012).
Molecular Function
Receptor for glutamate. The activity of this receptor is mediated by a G-protein that activates a phosphatidylinositol-calcium second messenger system and generates a calcium-activated chloride current

Strong Candidate


A de novo in-frame deletion variant in the GRM5 gene was identified by exome sequencing in an ASD case from the Simons Simplex Collection (Iossifov et al., 2012). Twelve rare variants in the GRM5 gene were identified in a cohort of 290 non-syndromic ASD cases that were not observed in 300 ethnically matched controls in a subsequent study (Kelleher III et al., 2012). Deletions with an overlapping region within an intron of the GRM5 gene were found to be statistically enriched in ADHD cases compared to controls (ten cases vs. one control, P = 1.36E-06) in Elia et al., 2011.

criteria met
See SFARI Gene'scoring criteriaWe 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.
