Summaries for Immunodeficiency 27b

UniProtKB/Swiss-Prot : 75 Immunodeficiency 27B: A form of Mendelian susceptibility to mycobacterial disease, a rare condition caused by impairment of interferon-gamma mediated immunity. It is 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. Clinical outcome severity depends on the degree of impairment of interferon-gamma mediated immunity. Some patients die of overwhelming mycobacterial disease with lepromatous-like lesions in early childhood, whereas others develop, later in life, disseminated but curable infections with tuberculoid granulomas. IMD27B commonly presents with recurrent, moderately severe infections with environmental mycobacteria or BCG. Salmonellosis is present in about 5% of patients.

MalaCards based summary : Immunodeficiency 27b, also known as immunodeficiency 27b, mycobacteriosis, autosomal dominant, is related to immunodeficiency 27a. An important gene associated with Immunodeficiency 27b is IFNGR1 (Interferon Gamma Receptor 1). Related phenotypes are immunodeficiency and osteomyelitis

OMIM : 57 Immunodeficiency-27B results from autosomal dominant (AD) IFNGR1 deficiency. Patients with AD IFNGR1 deficiency commonly present with recurrent, moderately severe infections with environmental mycobacteria or bacillus Calmette-Guerin (BCG). In contrast with patients with complete autosomal recessive (AR) IFNGR1 deficiency (IMD27A), cells from patients with AD IFNGR1 deficiency display residual responses to IFNG in vitro, indicating that the deficiency in IFNGR1 is partial. The clinical features of AD IFNGR1 deficiency are usually less severe than those in children with complete AR IFNGR1 deficiency, and mycobacterial infection often occurs later (mean age of 13.4 years vs 1.3 years), with patients having longer mean disease-free survival. In patients with AD IFNGR1 deficiency, M. avium tends to cause unifocal or multifocal osteomyelitis. Salmonellosis is present in about 5% of patients with AR or AD IFNGR1 deficiency, and other infections have been reported in single patients (review by Al-Muhsen and Casanova, 2008). (615978)
