  • Title: Controlled trial of serum isoelectric focusing in the detection of the cystic fibrosis gene.
    Author: Brock DJ, Hayward C, Super M.
    Journal: Hum Genet; 1982; 60(1):30-1. PubMed ID: 7076245.
    Abstract:
    Three independent observers assessed the discriminating power of serum isoelectric focusing in detecting the presence of the cystic fibrosis gene. On the basis of average scores, four out of 23 cystic fibrosis patients, six out of 22 heterozygotes, and three out of 16 controls were misclassified. However, the mean scores for the cystic fibrosis and heterozygote groups were significantly different to that for the control group. It is concluded that isoelectric focusing is insufficiently reliable to be used for diagnosis or heterozygote detection in cystic fibrosis, but that it does provide evidence for the presence of a protein associated with the mutant gene.
