Ectodermal dysplasias (EDs) include large group of syndromes that are clinically and genetically heterogeneous and are identified by anomalies in structures of ectodermal origin. Hereditary ectodermal dysplasia is a condition associated with defect of structures originating from ectoderm and is typically inherited as cross-linked recessive trait, more pronounced in males than in females. The frequency of different ectodermal dysplasias in a given population is highly variable. It is estimated to be 7 in 1,000 births. This case report is presented with an objective to show two patients, siblings, with ED. Both presented with classic symptoms of anodontia, hypohidrosis, and hypotrichosis.
