Abstract

Recurrent microdeletions and microduplications of a 600-kb genomic region of chromosome 16p11.2 have been implicated in childhood-onset developmental disorders. We report the association of 16p11.2 microduplications with schizophrenia in two large cohorts. The microduplication was detected in 12/1,906 (0.63%) cases and 1/3,971 (0.03%) controls (P = 1.2 x 10(-5), OR = 25.8) from the initial cohort, and in 9/2,645 (0.34%) cases and 1/2,420 (0.04%) controls (P = 0.022, OR = 8.3) of the replication cohort. The 16p11.2 microduplication was associated with a 14.5-fold increased risk of schizophrenia (95% CI (3.3, 62)) in the combined sample. A meta-analysis of datasets for multiple psychiatric disorders showed a significant association of the microduplication with schizophrenia (P = 4.8 x 10(-7)), bipolar disorder (P = 0.017) and autism (P = 1.9 x 10(-7)). In contrast, the reciprocal microdeletion was associated only with autism and developmental disorders (P = 2.3 x 10(-13)). Head circumference was larger in patients with the microdeletion than in patients with the microduplication (P = 0.0007).

  • Deletions and duplications of 16p11.2 have highly pleiotropic phenotypic effects, with strong links to ASD, ID, motor/developmental delay, dysmorphic features, and epilepsy/seizures.

    “Deletions and duplications of 16p11.2 have highly pleiotropic phenotypic effects, with strong links to ASD [8–19], ID [8, 10, 12, 14–16, 19–21], motor/developmental delay [8–10, 12, 13, 15–19, 22], dysmorphic features [8, 12, 16, 17, 22], and epilepsy/seizures [10, 12, 17].”
  • Schizophrenia appears to be associated more strongly with 16p11.2 duplications than with deletions.

    “Schizophrenia (SZ) appears to be associated more strongly with 16p11.2 duplications [9, 25–27].”
  • Bipolar disorder is reported in 16p11.2 duplication carriers.

    “Bipolar disorder is also reported in 16p11.2 duplication carriers [9, 14, 24].”
  • In a 2009 study, 21 duplications and 1 deletion were detected among 5,877 schizophrenia patients, indicating a 14.5-fold increased SZ risk in 16p11.2 duplication patients.

    “In a 2009 study, 21 duplications and 1 deletion were detected among 5,877 schizophrenia (SZ) patients, indicating a 14.5-fold increased SZ risk in 16p11.2 duplication patients [9].”
  • Evidence from the present work and earlier research indicates that 16p11.2 CNVs have much stronger effects than any common variant for complex common disorders.

    “there is clear evidence from this and prior studies (McCarthy et al., 2009) that 16p11.2 CNVs carry much larger effects than any common variant contributing to complex common disorders”

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.
