The genetic dissection of human primary immunodeficiency is expanding at full speed, in at least two directions. Some investigators pursue the dissection of well-known clinical phenotypes, for which the count of genetic etiologies seems to be endless, whereas others begin the search for inborn errors underlying new phenotypes, infectious and otherwise. The field of primary immunodeficiency is also expanding in other ways, with new therapeutic approaches, and with the care of patients in regions of the world where these diseases were unheard of less than a decade ago. Volume III includes overviews of PIDs in India and the Middle East as well as additional papers on new developments in primary immunodeficiencies (PIDs) and insights into PID pathophysiology.
