Project
SUMMIT is a pan-European research consortium that receives support from the Innovative Medicines Initiative (IMI). It aims at identifying markers that predict the risks of developing diabetes chronic micro- and macro-vascular complications with focus on diabetic nephropathy, diabetic retinopathy, and cardiovascular disease.
Experiment summary
SUMMIT Diabetic Kidney Disease GWAS is a genome-wide meta-analysis of diabetic kidney disease analyzed in subjects with type 1 or type 2 diabetes. Several different renal phenotypes were analyzed separately in type 1 and type 2 diabetics, and a combined analysis was also performed. The 1000G phase 1 March 2012 b37 reference panel was used for imputation.
DKD phenotypes were assessed for association with each SNP using a logistic regression for binary phenotypes and a linear regression for eGFR against genotype using an additive genetic model corrected for age, sex and duration of diabetes. P values were derived from a linear mixed model that took relatedness into account as well as age, sex and duration of diabetes.
Subsets of this dataset are available that include only type 1 diabetics or type 2 diabetics.
