Our data show that, in non-pHPT SCD patients, a negative association was found between fasting FeCa2+ and several biomarkers of hemolysis such as LDH, low hemoglobin or low hematocrit patients after adjustment on PTH, and thus independent of PTH-mediated distal tubular calcium reabsorption. The gene discussed is PTH; the disease is Schnyder corneal dystrophy.
