The 100+ ectodermal dysplasias are recognized and named based on the specific combination of symptoms shown in affected individuals. The pattern of these features is important when a physician tries to make a formal diagnosis.

In some types, teeth may be missing and nails may be defective, while in another type there may be missing teeth, inability to sweat, and sparse hair. Still another may have hearing loss and defects of the enamel of the teeth. Each combination of abnormalities may be a distinct ectodermal dysplasia and will have a unique name.
