A novel heterozygous missense variant in STAT3 (NM_139276.3: c.1250G > C, NP_644805.1: p.(Arg417Thr) was identified in a Danish family spanning five generations with diverse phenotypes consistent with autosomal dominant STAT3-Hyper-IgE-Syndrome (STAT3-HIES). Genetic analysis confirmed the absence of the variant in population databases, and computational predictions of pathogenicity were conflicting. Functional...
