Abstract

Attention deficit hyperactivity disorder (ADHD) is a common neurodevelopmental disorder, starting in early childhood and persisting into adulthood in the majority of cases. Family and twin studies have demonstrated the importance of genetic factors and candidate gene association studies have identified several loci that exert small but significant effects on ADHD. To provide further clarification of reported associations and identify novel associated genes, we examined 1,038 single-nucleotide polymorphisms (SNPs) spanning 51 candidate genes involved in the regulation of neurotransmitter pathways, particularly dopamine, norepinephrine and serotonin pathways, in addition to circadian rhythm genes. Analysis used within family tests of association in a sample of 776 DSM-IV ADHD combined type cases ascertained for the International Multi-centre ADHD Gene project. We found nominal significance with one or more SNPs in 18 genes, including the two most replicated findings in the literature: DRD4 and DAT1. Gene-wide tests, adjusted for the number of SNPs analysed in each gene, identified associations with TPH2, ARRB2, SYP, DAT1, ADRB2, HES1, MAOA and PNMT. Further studies will be needed to confirm or refute the observed associations and their generalisability to other samples.

  • Valid endophenotypes can be found at a higher rate in unaffected family members than in the general population.

    “it has been proposed that valid endophenotypes can be found at a higher rate in unaffected family members than in the general population 23,24.”

    From Increased neural responses to reward in adolescents and young adults with attention-deficit/hyperactivity disorder and their unaffected siblings (2015) · cites this paper as [24]

    The Introduction reports higher ADHD risk among siblings than in the general population, but it does not say that unaffected family members have endophenotypes at a higher rate. Searches for “endophenotype” and unaffected relatives found no passage in our copy making that comparison; the term appears only in a reference title. (LLM, conf=0.76)

  • Polymorphisms in PER2 may be associated with ADHD in children, but the association was not significant at study-wide or genome-wide level.

    “Brookes et al. (2006) in a genome-wide study provide speculative evidence that polymorphisms in PER 2 may be associated with ADHD in children, but the association was not significant at the study-wide or genome-wide level”

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.
