Ectodermal dysplasia is a group of disorders that affect the outer layer of tissue of the embryo. that helps make up the skin, sweat glands, hair, teeth, and nails.
Ectodermal dysplasia is a large group of inherited disorders characterised by a primary defect in hair, teeth, nails or sweat gland function, in addition to another abnormality in any tissue of ectodermal origin. These are ears, eyes, lips, mucous membranes of the mouth or nose, and the central nervous system. Ectodermal dysplasia occurs when the ectoderm of certain areas fails to develop normally. All ectodermal dysplasias are present from birth and are non-progressive. ectodermal dysplasias are caused by a genetic defect, they may be inherited or passed on down the family line.
Ectodermal dysplasias can be inherited in different patterns. Some cases of Ectodermal Dysplasia occur when a single altered copy of the gene is present, as this is sufficient to cause Ectodermal Dysplasia in the person who carries it despite that person having another, intact copy of the same gene. When we have children, we pass on half our genetic information. Therefore, a person affected with an Ectodermal Dysplasia will have a 50% (1 in 2) chance of passing the disorder on to each of their children regardless of the gender of the parent or the child.
