Corrigendum: Primary Immunodeficiency Diseases: An Update on the Classification from the International Union of Immunological Societies Expert Committee for Primary Immunodeficiency

In Table ​Table11 of the original manuscript, two gene defects were inadvertently omitted. These two defects (Cernunnos and DNA ligase IV deficiency) fall into the category of DNA recombination defects and lead to a radiosensitive form of SCID associated with microcephaly and developmental defects. These two genes have now been added to a revised Table ​Table11. Table 1 Combined immunodeficiencies.
