Here we present details on the 23 genes (among the 32 identified by the GPS approach on eGFRcys/BUN-validated, small set relevant variants, Fig. 4) that showed adequate fine-mapping resolution for the respective protein-relevant or kidney-tissue regulatory-relevant variant (PPA > = 10%) and novel evidence compared to the previous work7. A detailed description of the genes can be found in Supplementary Note 3.
