[Studies of the relationship between transferrin genetic polymorphism and diseases]

Genetic polymorphism of transferrin (Tf) was investigated in Han nationality population in Guangzhou area using isoelectric focusing technique. In addition, three diseases (Leukaemia, Heptocarcinoma, Systemic-lupus-erythematosis, SLE) were also typed for Tf and compared with that in normal population. The increased TfC1 gene frequency in acute myelocytic leukaemia (AML) patients was found (chi 2 = 4.16, P less than 0.05). The increased frequency of TfC1C1 was also observed (P less than 0.05). Relative Incident(RI) was 1.9 But TfC1 gene and TfC1C1 phenotype frequencies did not increase in ALL, CML and primary heptocarcinoma patients. It suggests that TfC1 may relative to AML in this area. Besides, the increased TfC1 gene frequency was observed in SLE patients (chi 2 x 6.15, P less than 0.025). RI of TfC1C2 was 2.3. It suggests that Tfc2 may relate to SLE in this area.
