Answer

In the United States, the carrier frequency is 1 per 90 individuals. The prevalence of Wilson disease is 1 per 30,000 individuals.

Worldwide, the incidence of Wilson disease is 10-30 million cases, and the heterozygote carrier rate is 1 case per 100 persons, with the genetic mutation frequency varying from 0.3%-0.7%. In Japan, the rate is 1 case per 30,000 population, compared with 1 case per 100,000 population in Australia. The increased frequency in certain countries is due to high rates of consanguinity. The fulminant presentation of Wilson disease is more common in females than in males.
