Novel STAT1 gain of function mutation and suppurative infections.

Chronic mucocutaneous candidiasis (CMCC) is a heterogeneous group of disorders characterized by non-invasive persistent Candida species infections of the skin, nails, and mucous membranes. Heterozygous dominant gain-of-function (GOF) mutations in signal transducer and activator of transcription 1 (STAT1) have been described as causing impaired STAT1 dephosphorylation, diminished IL-17- producing T-cell numbers, and CMCC (1, 2). Here, we report on the case of a 17-year-old boy who presented to our Department for CMCC. He was born preterm (36 weeks) to healthy non-consanguineous parents from Italy, by a pregnancy complicated by threatened miscarriage and gestosis. This article is protected by copyright.
