It is considered the most common human genetic disease. If the patient inherits the gene that causes the disease from both the father and the mother, then the course of the disease is severe and life expectancy decreases dramatically (most patients die from a heart attack or blood-stroke before the age of 30, including high infant mortality).
This is exactly the disease that we learn about from the media, as it manifests itself in sudden fainting (sometimes ending in death) during sports and sports competitions.
Despite the intuitive manifestations - the child does not hear from birth, the disease is usually recognized lateк − closer to 3 years old, when the child does not begin to speak
Only boys can have this illness, women are asymptomatic carriers of the disease. A new born child appears to be healthy, but by the age of 3-4 his parents begin to notice symptoms of a decrease in muscle strength
The disease develops only if the child inherits the broken gene from both the mother and the father. According to various sources, carriers of the disease are up to 19% of the population.
The disease has only one manifestation - sudden fainting. Any of the fainting spells can be fatal. There is an effective drug treatment for the disease, which must be combined with the mandatory limitation of physical activity.
