Hypohidrotic ectodermal dysplasia has several different inheritance patterns. Most cases are inherited in an X-linked pattern and are caused by mutations in the EDA gene. A condition is considered X-linked if the mutated gene that causes the disorder is located on the X chromosome, one of the two sex chromosomes. Pai SY, Levy O, Jabara HH, et al. They are caused by mutations in various genes ; the mutations may be inherited from a parent, or normal genes may become mutated at the time of egg or sperm formation, or after fertilization. J. Hum.
