Summary

Ectodermal dysplasia with immunodeficiency-1 (EDAID1) is an X-linked recessive disorder that characteristically affects only males. Affected individuals have onset of recurrent severe infections due to immunodeficiency in early infancy or in the first years of life. There is increased susceptibility to bacterial, pneumococcal, mycobacterial, and fungal infections. Laboratory studies usually show dysgammaglobulinemia with low IgG subsets and normal or increased IgA and IgM, consistent with impaired 'class-switching' of B cells, although immunologic abnormalities may be subtle compared to the clinical picture, and B- and T-cell numbers are usually normal. There is a poor antibody response to polysaccharide vaccinations, particularly pneumococcus; response to other vaccinations is variable. Patients also have features of ectodermal dysplasia, including conical incisors, hypo/anhidrosis, and thin skin or hair. Severely affected individuals may also show lymphedema, osteopetrosis, and, rarely, hematologic abnormalities. The phenotype is highly variable, likely due to different hypomorphic mutations, and may be fatal in childhood. Intravenous immunoglobulins and prophylactic antibiotics are used as treatment; some patients may benefit from bone marrow transplantation. Although only males tend to be affected with immunodeficiency, many patients inherit a mutation from a mother who has mild features of IP or conical teeth (summary by Doffinger et al., 2001, Orange et al., 2004, Roberts et al., 2010, Heller et al., 2020).
