SLC7A9 and chronic kidney disease: Of the 16 SNPs, UMOD (hazard ratio = 0.83(0.70, 0.99), P-value = 0.03), PIP5K1B (hazard ratio = 0.85(0.75, 0.96), P-value = 0.01) and SLC7A9 (hazard ratio = 0.86(0.76, 0.98) P-value = 0.02) was associated with time to stage 3B CKD (eGFR<45 mls/min/1.73 m2) at the 0.05 threshold for significance.
