COL4A3 and diabetic kidney disease: As our previous GWAS also identified a common missense variant associated with DKD, namely the COL4A3 missense variant rs55703767 [10], we further extended the analysis to more common variants with an MAF ≤10%, resulting in suggestive association at NAT16 and SLC10A6. Through look-ups of the lead SNPs behind the gene-aggregate results, replication was found for NAT16 and LTA in the FinnGen cohort (ESM Table 3).
