Iron 37-41 haptoglobin Homo sapiens 0-11 26228081-7 2015 Stratified analysis by haptoglobin phenotype was performed to determine effect of haptoglobin phenotype on serum iron parameter differences between PD cases and controls and to investigate its role in the protective effect of smoking on PD risk. Iron 113-117 haptoglobin Homo sapiens 82-93 26228081-11 2015 CONCLUSIONS: Our results report for the first time that the haptoglobin phenotype may be a contributor of iron levels abnormalities in PD patients. Iron 106-110 haptoglobin Homo sapiens 60-71
