Polymorphisme Physiologique Des Enzymes Erythrocytaires

Pages 135-146 | Published online: 17 May 2016
 

Summary

The pattern obtained by evidencing the activity of certain enzymes following electrophoresis of red cell hemolysates, varies from one individual to another.

With regard to the enzymes under consideration (acid phosphatase, phosphoglucomutase, adenylate kinase, adenosine deaminase, glutamic-pyruvic transaminase, phosphogluconate deshydrogenase, etc...), this polymorphism is determined by a simple genetic system, does not correspond to any pathology, and belongs therefore to the concept of “blood group”.

Besides their theoretical interest, these group systems are very useful for resolving some problems of applied human geneties, particularly for the diagnosis of mono- or dizygotic twins and for medico-legal cases of disputed paternity.

Resume

L’image obtenue en mettant en évidence l’activité de certains enzymes après électrophorèse d’hémolysats érythrocytaires, varie selon les individus.

Pour les enzymes considérés (phosphatase acide, phosphoglucomutase, adénylate kinase, adénosine déaminase, transaminase glutamique-pyruvique, phosphogluconate déshydrogénase, etc...), ce polymorphisme enzymatique est déterminé par un système génétique simple, ne correspond à aucune pathologie et rentre donc dans le concept de “groupe sanguin”.

Outre leur intérêt théorique, ces systèmes de groupes sont très utiles pour résoudre certains problèmes de génétique humaine appliquée, en particulier le diagnostic de mono- ou de dizygotie de jumeaux ainsi que les expertises médico-légales de filiation.

Samenvatting

Het electroforese patroon van sommige enzymen uit erythrocytenlysaten verschilt naargelang het individu.

Voor sommige enzymen (zure phosphatase, phosphoglucomutase, adenylaatkinase, adenosine deaminase, glutamo-pyrivaat transaminase, phosphogluconaat dehydrogenase e.a.) wordt dit polymorphisme genetisch bepaald, staat ze met geen enkele pathologie in verband en stemt ze dus overeen met het begrip bloedgroep.

Dit genetisch polymorfisme kan dan ook betrokken worden bij genetisch onderzoek zoals de diagnose van mono- of dizygotische tweelingen en bepalingen van vaderschap.
