Transferrin subtypes in cystic fibrosis

The molecular polymorphism and quantitative data of serum transferrin (Tf) were ascertained in a group of fibrocystic patients, their parents and controls. Quantitative rates of pre-albumin, retinol binding globulin (RBG) and alpha-1-glycoprotein were also investigated as a reference for the evaluation of Tf quantitative data. Neither different allele distributions nor abnormal electrophoretic patterns were observed among CF patients. A slight lowering of Tf, pre-albumin and RBG, probably due to malnutritional condition in CF subjects was found.
