Characteristics of mycobacterial infection in patients with immunodeficiency and nuclear factor-kappaB essential modulator mutation, with or without ectodermal dysplasia.

Hypomorphic mutations of the nuclear factor kB essential modulator gene cause ectodermal dysplasia and immunodeficiency. Affected patients have increased susceptibility to mycobacterial disease including cutaneous manifestations. We describe clinical and histopathologic characteristics of 5 patients with nuclear factor kB essential modulator gene mutations and mycobacterial infections, two of whom had myco- bacterial cutaneous infections.
