IMD33 results from X-linked recessive NEMO deficiency, which is associated with various other diseases, including immunodeficiency with hypohidrotic ectodermal dysplasia (300291), together with osteopetrosis and lymphedema (300301) in some patients, and immunodeficiency without ectodermal dysplasia (300584). In contrast with patients with these other forms of X-linked recessive NEMO deficiency, who display a broad susceptibility to infections, infections in IMD33 patients are mostly limited to mycobacterial disease, with M. avium complex being the most common cause. Furthermore, IMD33 patients lack developmental features suggestive of hypohidrotic ectodermal dysplasia. Monocytes from IMD33 patients have intrinsic defects in T cell-dependent IL12 (see 161561) production, resulting in impaired IFNG (147570) production. The prognosis of IMD33 patients is variable (review by Al-Muhsen and Casanova, 2008). [from OMIM]
