Ectodermal dysplasia (ED) is a rare hereditary disorder involving two or more of the ectodermal structures, which include the skin, hair, nails, teeth, and sweat glands. Hypohidrotic ectodermal dysplasia (HED) is the most common type of ED. HED is usually an X-linked recessive (XLR) disorder affecting predominantly males. However, Autosomal recessive (AR) and Autosomal dominant (AD) forms have been described in rare cases. Here, we report three cases of HED showing different patterns of inheritance with similar phenotypes; one with a classic X-linked inheritance and the other two include female siblings with an Autosomal recessive inheritance. Keywords: Hypohidrotic ectodermal dysplasia, Xlinked, Autosomal recessive
