Genetic instruments for Mendelian Randomization analyses of childhood and adult BMI

<p>This file lists variants used as instrumental variables for the manuscript "Separating the effects of childhood and adult body size on inflammatory arthritis: a Mendelian randomisation study".</p> <p><br></p> <p>We selected independent (linkage disequilibrium threshold of r2<0.001 using PLINK and a reference panel of 10,000 randomly selected Europeans from UK Biobank) genome-wide significant (p<5x10-8) SNPs, resulting in 313 childhood and 580 adult body size instruments. For multivariable MR, we repeated LD clumping for the combined set of SNPs from both exposures.  </p>
