Our previous GWAS on albuminuria, as measured by 24-hour AER, identified five single nucleotide polymorphisms (SNPs) in the GLRA3 gene that were associated with albuminuria with genome-wide significance (p-value = 1.5 × 10−9 for rs10011025) in Finnish individuals with type 1 diabetes in the Finnish Diabetic Nephropathy Study (FinnDiane). Here, GLRA3 is linked to type 1 diabetes mellitus.
