Abstract

Obesity has become a major worldwide challenge to public health, owing to an interaction between the Western 'obesogenic' environment and a strong genetic contribution. Recent extensive genome-wide association studies (GWASs) have identified numerous single nucleotide polymorphisms associated with obesity, but these loci together account for only a small fraction of the known heritable component. Thus, the 'common disease, common variant' hypothesis is increasingly coming under challenge. Here we report a highly penetrant form of obesity, initially observed in 31 subjects who were heterozygous for deletions of at least 593 kilobases at 16p11.2 and whose ascertainment included cognitive deficits. Nineteen similar deletions were identified from GWAS data in 16,053 individuals from eight European cohorts. These deletions were absent from healthy non-obese controls and accounted for 0.7% of our morbid obesity cases (body mass index (BMI) >or= 40 kg m(-2) or BMI standard deviation score >or= 4; P = 6.4 x 10(-8), odds ratio 43.0), demonstrating the potential importance in common disease of rare variants with strong effects. This highlights a promising strategy for identifying missing heritability in obesity and other complex traits: cohorts with extreme phenotypes are likely to be enriched for rare variants, thereby improving power for their discovery. Subsequent analysis of the loci so identified may well reveal additional rare variants that further contribute to the missing heritability, as recently reported for SIM1 (ref. 3). The most productive approach may therefore be to combine the 'power of the extreme' in small, well-phenotyped cohorts, with targeted follow-up in case-control and population cohorts.

  • 16p11.2 deletions are associated with macrocephaly and obesity, while duplications often lead to microcephaly and low body weight/BMI.

    “Deletions of 16p11.2 are associated with increased head circumference (macrocephaly) [10, 12, 17, 23] and obesity [10, 12, 16, 20], whereas duplications often result in below average head size (microcephaly) [10, 17, 23, 24] and low body weight/BMI [10, 24].”
  • In individuals with neurodevelopmental disorders, genetic screenings find 16p11.2 deletions at rates of 0.25-2.9% and duplications at rates of 0.15-0.78%.

    “Data compiled from eight studies [13, 15–17, 20, 24, 26, 33] screening individuals with either ASD, ID, developmental delay (DD), dysmorphic features (DF), multiple congenital anomalies (MCA), obesity, or seizures find 16p11.2 deletions at rates of 0.25–2.9%, and duplications at rates between 0.15–0.78% (Table 1).”
  • 16p11.2 deletions are present at higher-than-expected rates in obese individuals and are more prevalent in developmental delay patients with obesity than those without obesity.

    “16p11.2 deletions are present at higher-than-expected rates in obese individuals [31], and are more prevalent in developmental delay (DD) patients with obesity than those without obesity [20].”
  • Recurrent ASD-associated CNVs such as 16p11.2 are linked not only to ASD but also to schizophrenia, epilepsy, ADHD, and obesity.

    “Variability of phenotype is also characteristic of recurrent ASD-associated CNVs, such as 16p11.2, which has been linked not only to ASD but also to schizophrenia, epilepsy, ADHD, and obesity (Mccarthy et al., 2009; Shinawi et al., 2010; Walters et al., 2010; Weiss et al., 2008).”

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.
