Ehlers–Danlos syndromes are estimated to occur in about one in 5,000 births worldwide. Initially, prevalence estimates ranged from one in 250,000 to 500,000 people, but these estimates were soon found to be too low, as more was studied about the disorders, and<unk>  professionals became more adept at diagnosis. EDS may be far more common than the currently accepted estimate due to the wide range of severities with which the disorder presents. The prevalence of the disorders differs dramatically. The most commonly occurring is hypermobile EDS, followed by classical EDS. The others are very rare. For example, fewer than 10 infants and children with dermatosparaxis EDS have been described worldwide. Some types of EDS are more common in Ashkenazi Jews. For example, the chance of being a carrier for dermatosparaxis EDS is one in 2,000 in the general population, whereas the prevalence of this variation in the Ashkenazi Jews is one in 248.
