Abstract

We used genome-wide single nucleotide polymorphism (SNP) data to search for the presence of copy number variants (CNVs) in 882 patients with bipolar disorder (BD) and 872 population-based controls. A total of 291 (33%) patients had an early age-at-onset < or =21 years (AO < or =21 years). We systematically filtered for CNVs that cover at least 30 consecutive SNPs and which directly affect at least one RefSeq gene. We tested whether (a) the genome-wide burden of these filtered CNVs differed between patients and controls and whether (b) the frequency of specific CNVs differed between patients and controls. Genome-wide burden analyses revealed that the frequency and size of CNVs did not differ substantially between the total samples of BD patients and controls. However, separate analysis of patients with AO < or =21 years and AO>21 years showed that the frequency of microduplications was significantly higher (P=0.0004) and the average size of singleton microdeletions was significantly larger (P=0.0056) in patients with AO < or =21 years compared with controls. A search for specific BD-associated CNVs identified two common CNVs: (a) a 160 kb microduplication on 10q11 was overrepresented in AO < or = 21 years patients (9.62%) compared with controls (3.67%, P=0.0005) and (b) a 248 kb microduplication on 6q27 was overrepresented in the AO< or = 21 years subgroup (5.84%) compared with controls (2.52%, P=0.0039). These data suggest that CNVs have an influence on the development of early-onset, but not later-onset BD. Our study provides further support for previous hypotheses of an etiological difference between early-onset and later-onset BD.

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.
