Hypohidrotic ectodermal dysplasia (HED) is a genetic disorder which involves a complex group of inherited conditions. This condition is characterised by the failed development of two or more ectodermal derived anatomic structure; for example, the skin, hair, nails, teeth, and sweat glands. It is a phenotypically heterogenous group of illnesses including anodontia with conical teeth, generalised spacing, reduced ability to sweat, very less hair growth, etc. The pattern of inheritance of HED varies from person to person depending on the type of ectodermal dysplasia (ED). The patterns include X-linked recessive, X-linked dominant, autosomal dominant, autosomal recessive, and spontaneous mutation. There is one such common type of ED more in female than male. It is an X-linked HED (XLHED), characterised by hypohidrosis, sparse hair, and teeth abnormalities. The other type can affect both male and female equally and may be inherited in different ways. The present case is a 21-year-old male who presented with hair, teeth, and sweat gland abnormalities.
