except for rs11847697, which did not have a highly correlated SNP (r2 < 0.7) and was therefore not included in SNP-GRSSs. Proxy SNP information appears in Additional file 1: Table S1b. BMI and obesity associated CNVs were catalogued from research published between January 2008 and January 2012 via PubMed search (Additional file 2: Table S2). Case reports, typical of monogenic inheritance, were not included in the catalogue as the focus of the current study was on common complex obesity.
