Disease definition Hypohidrotic ectodermal dysplasia (HED) is a genetic disorder of ectoderm development characterized by malformation of ectodermal structures such as skin, hair, teeth and sweat glands. In females, who have two copies of the X chromosome, one altered copy of the gene in each cell often leads to less severe features of the condition. In some cases, hyperthermia can cause life-threatening health problems. 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. Sweating is a major way that the body controls its temperature; as sweat evaporates from the skin, it cools the body.
