[Polyacrylamide gel disc-electrophoresis of serum proteins in patients with Turner's, Klinefelter's and Down's syndromes].

High efficiency of polyacrylamide gel disk electrophoresis was used for detailed studies of dislipoproteinemia observed in Shereshevskii-Turner, Klinefelter and Down syndromes. Occurrence of protein fractions typical for each of the syndromes was due to frequency of phenotypes in the protein systems Hp and Yc of the syndromes studied.
