To the best of our knowledge, only one other study has delved into this aspect in more detail, which did not find a significant difference in PTH between ADPKD patients with or without phosphate wasting at early CKD stages (G1/2), although their cohort was smaller (n = 13 vs n = 86, with and without phosphate wasting) [4]. The gene discussed is PTH; the disease is chronic kidney disease.
