In the United States, the incidence of<unk>  is estimated to be one per 20,000 live births. An estimated 20,000 to 50,000 people are affected by<unk>  in the United States. The most common types are I, II, III, and IV, while the rest are very rare. Type I is the most common and has been reported to be around three times more common than type II. The prevalence of types III and IV is less certain. In a 1989 study in Denmark, type I was found to comprise 71% of cases and type II 12% of cases, with other types comprising the other 17%. In a 2015 study in Sweden, type I was nearly six times more common than type III and nearly four times more common than type IV. Most people with<unk>  receive it from a parent, but in many cases, it is a brand new (de novo or "sporadic") mutation in a family. Among a study of patients with survivable types of<unk> ,<unk>  type III is most often de novo (85%), followed by type IV (50%) and type I (34%). Some populations can have a higher incidence of<unk>  than would be otherwise expected if they have a larger than average number of carriers of the recessive forms of the disease.
