How common is Andermann Syndrome?
Andermann Syndrome is most common in French Canadian populations in a northwestern region of Quebec. In this area, the condition occurs in approximately 1 in 2,000 births. Andermann Syndrome is rarely seen in other areas of the world. In 2019 there was a case reported in a Roma individual in Bulgaria suggesting that Andermann Syndrome may be more common in this population. However, further studies are required to confirm this.
