Nineteen similar deletions were identified from GWAS data in 16053 individuals from 8 European cohorts; such deletions was absent from healthy non-obese controls and accounted for 0.7% of our morbid obesity cases (p = 6.4x10-8, OR = 43). These findings highlight a promising strategy for identifying missing heritability in obesity and other complex traits, in which insights from rare extreme cases can be used to elucidate the basis for more common phenotypes. The expression data was analysed for 2 obese subjects carrying a deletion on 16p11.2. There are no replicates or controls.

Following fragmentation,15 ug of cRNA were hybridized for 16 hr at 45C on Human U133 Plus 2.0 arrays. Arrays were washed and stained in the Affymetrix Fluidics Station 450. Qiagen Lipid Tissue RNA extraction kit. Biotinylated cRNA were prepared according to the standard Affymetrix protocol from 3 ug total RNA (Expression Analysis Technical Manual, 2001, Affymetrix). Gene expression levels were normalised using the Robust Multiarray Average (RMA) method.
