Immunodeficiency 31B also referred to as IMD31C, is a congenital immunodeficiency with highly variable manifestations resulting from autosomal dominant gain-of-function mutations in STAT1.

Clinical featuresThis section has been translated automatically.
Most patients present in infancy or early childhood with chronic mucocutaneous candidiasis (CMC - Yamazaki Y et al 2014). Other highly variable features include recurrent bacterial, viral, mycotic, and mycoplasmal infections, disseminated dimorphic fungal infections, enteropathy with villous atrophy, and autoimmune disorders such as hypothyroidism or diabetes mellitus. A subset of patients exhibit apparent nonimmunologic features, including osteopenia, delayed puberty, and intracranial aneurysms (Uzel G et al. 2013).
