Interestingly, the prevalence of pretransplantation hyperparathyroidism was very high (mean pretransplantation PTH: 88 pmol/L) (Figure 5) and PTH levels were similar amongst all modes of dialysis during this period and did not correlate with duration on dialysis prior to renal transplant (Figure 6). The gene discussed is PTH; the disease is hyperparathyroidism.
