Genetische Risikofaktoren
Malignant hyperthermia of anesthesia is primarily linked to genetic mutations that affect the body's ability to regulate calcium levels in muscle cells. These mutations can lead to a dangerous reaction to certain anesthetic drugs. The condition is inherited in an autosomal dominant pattern, meaning a single copy of the altered gene in each cell is sufficient to increase the risk of the disorder.
RYR1 gene mutation: Mutations in the RYR1 gene are the most common genetic cause of malignant hyperthermia. This gene provides instructions for making a protein that plays a critical role in calcium release within muscle cells. Abnormalities in this gene can lead to uncontrolled calcium release, triggering the symptoms of malignant hyperthermia.
CACNA1S gene mutation: Mutations in the CACNA1S gene are another genetic risk factor for malignant hyperthermia. This gene is responsible for encoding a protein that forms part of a channel involved in calcium transport in muscle cells. Changes in this gene can disrupt normal calcium flow, contributing to the development of malignant hyperthermia.
Autosomal dominant inheritance pattern: Malignant hyperthermia is inherited in an autosomal dominant manner. This means that having just one copy of the mutated gene from either parent can increase the risk of developing the condition. Individuals with a family history of malignant hyperthermia are at a higher risk due to this inheritance pattern.

Wie Gene Krankheiten verursachen können
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.
