What is the prevalence of Paramyotonia congenita?
How many people does Paramyotonia congenita affect? Does it have the same prevalence in men and women? And in the different countries?
Paramyotonia congenita is a rare genetic disorder characterized by muscle stiffness and weakness. It is caused by mutations in the SCN4A gene. The prevalence of this condition is estimated to be around 1 in 100,000 individuals worldwide. Although it is considered a rare disorder, the exact prevalence may vary among different populations. Paramyotonia congenita is inherited in an autosomal dominant manner, meaning that an affected individual has a 50% chance of passing the condition to their offspring. Early diagnosis and management can help alleviate symptoms and improve quality of life for those affected.
Paramyotonia congenita is a rare genetic disorder that affects the muscles and causes muscle stiffness or weakness. It is inherited in an autosomal dominant pattern, meaning that a person only needs to inherit one copy of the mutated gene from either parent to develop the condition.
The prevalence of Paramyotonia congenita is estimated to be very low, with only a few hundred cases reported worldwide. Due to its rarity, it is considered an orphan disease. The exact prevalence is difficult to determine as many cases may go undiagnosed or misdiagnosed.
Paramyotonia congenita is more commonly found in certain populations, such as individuals of Scandinavian or Dutch descent. It typically manifests in childhood or early adulthood, with symptoms worsening during cold temperatures or after exercise.
While the prevalence of Paramyotonia congenita is low, it is important for individuals with symptoms to seek medical evaluation and genetic testing for an accurate diagnosis. Early detection and management can help alleviate symptoms and improve quality of life for those affected.

I have also read that it is more prevalent in Scandinavian countries.
