Menschen haben mehr als 20.000 Gene, von denen jedes eine oder einige wenige spezifische Funktionen im Körper erfüllt. Ein Gen weist den Körper an, Laktose aus Milch zu verdauen, ein anderes zeigt dem Körper, wie starke Knochen aufgebaut werden, und ein weiteres verhindert, dass sich Körperzellen unkontrolliert zu teilen beginnen und sich zu Krebs entwickeln. Da all diese Gene zusammen die Bauanleitung für unseren Körper darstellen, kann ein Defekt in einem dieser Gene schwerwiegende gesundheitliche Folgen haben.
Durch jahrzehntelange genetische Forschung kennen wir den genetischen Code jedes gesunden/funktionalen menschlichen Gens. Wir haben auch festgestellt, dass an bestimmten Positionen eines Gens manche Personen einen anderen genetischen Buchstaben haben können als Sie. Diese Hotspots nennen wir „genetische Variationen“ oder kurz „Varianten“. In vielen Fällen konnten Studien zeigen, dass das Vorhandensein des genetischen Buchstabens „G“ an einer bestimmten Position gesund ist, während das Vorhandensein des Buchstabens „A“ an derselben Stelle die Genfunktion stört und eine Krankheit verursacht. Genopedia ermöglicht es Ihnen, diese Varianten in Genen einzusehen und fasst zusammen, was wir aus der wissenschaftlichen Forschung darüber wissen, welche genetischen Buchstaben (Genotypen) gute oder schlechte Auswirkungen auf Ihre Gesundheit oder Ihre Eigenschaften haben.
