Anhidrotic Ectodermal Dysplasia-Immunodeficiency-Osteopetrosis-Lymphedema Syndrome

This syndrome is characterized by severe immunodeficiency, osteopetrosis, lymphedema and anhidrotic ectodermal dysplasia.

Epidemiology

It has been described in a few unrelated male patients born to mothers with mild incontinentia pigmenti.

Clinical description

The first two reported children died before three years of age from multiple infections with Gram-positive cocci, Gram-negative bacilli, mycobacteria, and fungi.

Etiology

The syndrome is classified as a X-linked osteopetrosis and is caused by mutations in the IKBKG (NEMO) gene (Xq28).
