The calculated risk factors for patients with AKI receiving dialysis were identified as rising serum creatinine (RR = 16.39, 95 % CI; 1.72–156.64, P = 0.015), hypernatremia (RR = 1.13, 95 % CI; 1.01–1.27, P = 0.041), hyperphosphatemia (RR = 1.66, 95 % CI; 1.19–2.33, P = 0.003) and hypermagnesemia (RR = 7.01, 95 % CI; 1.53–32.15, P = 0.012) and CPK > median value (RR = 13.91, 95 % CI; 1.66–116.41, P = 0.015). The gene discussed is PIK3C2A; the disease is Hypermagnesemia.
