Birth incidence is 1 case per 6,000 population, with a prevalence of 1 case per 10,000 population.

Factors that hamper accurate assessment of incidence and prevalence include under-recognition of less severe phenotypes, high spontaneous mutation rate (approximately two thirds), marked variability of symptoms (even within specific kindreds of affected individuals), and reluctance of asymptomatic parents and relatives to undergo diagnostic testing related to concerns of uninsurability and social stigma.
