The syndrome is thought to be inherited as an autosomal recessive genetic trait, meaning that in order to manifest symptoms, a person must inherit a gene for<unk>  from both parents. As it is also autosomal (not linked to either of the genes that determine gender), it can manifest in both men and women. Those with only one gene are carriers, and they typically manifest no symptoms; in the event that a person inherits both genes, symptoms usually appear before one year of age.
