Since the discovery of the genetic basis of DOCK8 immunodeficiency syndrome (DIDS) in 2009, several hundred patients worldwide have been reported, validating and extending the initial clinical descriptions. Importantly, the beneficial role of hematopoietic stem cell transplantation for this disease has emerged, providing impetus for improved diagnosis. Additionally, several groups have further elucidated the biological functions of DOCK8 in the immune system that help explain disease pathogenesis. Here, we summarize these recent developments.
