Abstract

Mendalian susceptibity to mycobacterial disease (MSMD) is a condition caused by selective susceptibility to weakly virulent bacteria in otherwise healthy patients without additional immunological abnormalities. It is an inherited, genetic disorder with variety of clinical presentation. Diagnosis is mandatory because the illness may get precipitated by BCG and other live vaccines. Estimating interleukin in serum can be considered as a diagnostic test. Immunological analysis is mandatory for confirming the diagnosis. Mutation analysis can be done to confirm the mutation and hence, prevent the disease in the next sibling by testing in utero. This condition can be treated with ATT as the first line treatment. If ineffective, can be given other modalities of treatment described. But relapses are common. Stem cell transplantation is the definitive treatment. We describe an infant diagnosed as partial dominant interferon gamma receptor deficiency (IFNGR1) deficiency, who responded to ATT.
