Exome-first Approach Identified Novel Homozygous Dedicator of Cytokinesis 8 (DOCK8) Mutations in Three Unrelated Iranian Pedigrees Suspected with Hyper-IgE Syndrome.

The prevalence of primary immunodeficiency (PID) is rather high in Iran compared to the world average, mainly due to the high rate of consanguineous marriage. Despite that, little genetic information is available about primary immunodeficiencies in Iran. Autosomal recessive hyper IgE syndrome (AR-HIES) is a severe type of immunodeficiency, mainly caused by mutations in the dedicator of cytokinesis 8 (DOCK8).
