Naegeli syndrome

Naegeli syndrome (Naegeli-Franceschetti-Jadassohn syndrome) is a rare autosomal dominant form of ectodermal dysplasia, characterized by reticular skin pigmentation, diminished function of the sweat glands, the absence of teeth and hyperkeratosis of the palms and soles. One of the most striking features is the absence of fingerprint lines on the fingers.

It was named after Oskar Naegeli.
