Ectodermal Dysplasia
Ectodermal dysplasia makes for a group of disorders. It is characterized by the abnormal development of two or more ectodermal structures. Allow us to explain: the word ectodermal describes one of the germ layers of the embryo. This layer is responsible for the prenatal development of stuff as necessary as the epidermis, the nervous system, and the neural tissue.
In other words, people with ectodermal dysplasia exhibit stuff like abnormal nails or teeth, a cleft lip, a very large forehead, or a low nasal bridge. In some cases, the condition can also give way to learning disabilities.
