Ectodermal dysplasia and immunodeficiency 1: A form of ectoderma dysplasia, a heterogeneous group of disorders due to abnormal development of two or more ectodermal structures. Characterized by absence of sweat glands, sparse scalp hair, rare conical teeth and immunological abnormalities resulting in severe infectious diseases.
Ectodermal dysplasia, anhidrotic, with immunodeficiency, osteopetrosis and lymphedema: A form of ectoderma dysplasia, a heterogeneous group of disorders due to abnormal development of two or more ectodermal structures. Characterized by the association of anhidrotic ectodermal dysplasia with severe immunodeficiency, osteopetrosis and lymphedema.
Immunodeficiency, NEMO-related, without anhidrotic ectodermal dysplasia: Patients manifest immunodeficiency not associated with other abnormalities, and resulting in increased susceptibility to infections. Patients suffer from multiple episodes of infectious diseases.
Immunodeficiency 33: An X-linked recessive form of Mendelian susceptibility to mycobacterial disease, a rare condition characterized by predisposition to illness caused by moderately virulent mycobacterial species, such as Bacillus Calmette-Guerin (BCG) vaccine, environmental non-tuberculous mycobacteria, and by the more virulent Mycobacterium tuberculosis. Other microorganisms rarely cause severe clinical disease in individuals with susceptibility to mycobacterial infections, with the exception of Salmonella which infects less than 50% of these individuals.
Recurrent isolated invasive pneumococcal disease 2: Recurrent invasive pneumococcal disease (IPD) is defined as two episodes of IPD occurring at least 1 month apart, whether caused by the same or different serotypes or strains. Recurrent IPD occurs in at least 2% of patients in most series, making IPD the most important known risk factor for subsequent IPD.
Incontinentia pigmenti: A genodermatosis usually prenatally lethal in males. In affected females, it causes abnormalities of the skin, hair, eyes, nails, teeth, skeleton, heart, and central nervous system. The prominent skin signs occur in four classic cutaneous stages: perinatal inflammatory vesicles, verrucous patches, a distinctive pattern of hyperpigmentation and dermal scarring.
