[Genetic variants of human albumin: structural characterization of allotypes used as references for electrophoretic classification].
Eight different types of genetic variants of albumin are observed in the French population. The analysis of electrophoretic patterns of sera containing these variants, performed a three different pHs (8.6, 5.0 and 6.9) after addition of a reference protein (transferrin), allows the identification each variant by a quantitative estimation of its relative mobilities. The accuracy and reproducibility of the technique make it a useful reference method, commonly employed for studying European variants. The samples used as references for five genetic variant types, proalbumins Christchurch and Lille, albumins Vanves, B and Reading, were subjected to sequence analysis to determine the nature and localization of their structural change. Together with the mutations of albumins Gent and Roma previously described, the data presented here make available seven reference specimens for which the structural changes are characterized out of the eight variants known to exist in France.
