Abstract

Hakon Hakonarson and colleagues report a genome-wide copy number variation study in 3,506 cases of attention-deficit hyperactivity disorder. The authors identify a statistically significant enrichment of CNVs impacting metabotropic glutamate receptor genes. Attention deficit hyperactivity disorder (ADHD) is a common, heritable neuropsychiatric disorder of unknown etiology. We performed a whole-genome copy number variation (CNV) study on 1,013 cases with ADHD and 4,105 healthy children of European ancestry using 550,000 SNPs. We evaluated statistically significant findings in multiple independent cohorts, with a total of 2,493 cases with ADHD and 9,222 controls of European ancestry, using matched platforms. CNVs affecting metabotropic glutamate receptor genes were enriched across all cohorts (P = 2.1 × 10−9). We saw GRM5 (encoding glutamate receptor, metabotropic 5) deletions in ten cases and one control (P = 1.36 × 10−6). We saw GRM7 deletions in six cases, and we saw GRM8 deletions in eight cases and no controls. GRM1 was duplicated in eight cases. We experimentally validated the observed variants using quantitative RT-PCR. A gene network analysis showed that genes interacting with the genes in the GRM family are enriched for CNVs in ∼10% of the cases (P = 4.38 × 10−10) after correction for occurrence in the controls. We identified rare recurrent CNVs affecting glutamatergic neurotransmission genes that were overrepresented in multiple ADHD cohorts.

  • ADHD-associated CNVs span several glutamate receptor genes and the gene encoding neuropeptide Y.

    “Finally, ADHD-associated CNVs also span several glutamate receptor genes, which are essential for neuronal glutamatergic transmission 44 , and the gene encoding neuropeptide Y, which is involved in signalling in the brain and autonomic nervous system 45 .”

    From Attention-deficit/hyperactivity disorder (2015) · cites this paper as [44]

    The paper reports ADHD-associated CNVs directly affecting several metabotropic glutamate receptor genes (Abstract, page not supplied). It also reports an association at NLN, which inactivates neuropeptide Y; it does not report that its CNVs span the gene encoding neuropeptide Y (main text indexed under Abstract, page not supplied). (LLM, conf=0.90)

  • Alterations in glutamate receptors (GRM-1, GRM-5, GRM-7 and GRM-8) have been associated with ADHD.

    “Alterations in glutamate receptors (GRM-1, GRM-5, GRM-7 and GRM-8) have been associated with ADHD [124].”
  • In a genome-wide study, copy-number variations in genes interacting with metabotropic glutamate receptors were enriched in 10% of ADHD cases.

    “in a genome-wide study of children with ADHD and matched controls, variations in copy number within genes interacting with metabotropic glutamate receptors were enriched in 10% of ADHD cases (Elia et al 2011).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
