Clinical manifestations associated with novel mutations in the coiled-coil domain of STAT1

Abstract

Monoallelic mutations in STAT1 are associated with a variety of clinical patterns. We studied patients with novel mutations in the coiled-coil domain of STAT1. We found that clinical manifestations can vary from mild Candida infections limited to the oropharyx to serious serial strokes and skin cancer. Autoimmune manifestations were found to be rare and limited to hypothyroidism. Immune evaluations were normal or near normal in all patients with the exception of anergy to Candida. Mutation in the coiled-coil domain results in susceptibility to mucus membrane candidiasis as well as brain vascular anomalies. Statement of novelty: We describe novel mutations in the coiled-coil domain of STAT1.
