Abstract:
Activated phosphoinositide 3-kinase δ (PIK3CD) syndrome is a combined immunodeficiency,caused by PIK3CD gain-of-function mutations,which encodes the catalytic subunit of PIK3CD.These patients presented with early onset sinopulmonary infections,lymphoproliferation,herpesvirus infections,autoinflammatory disease,lymphoma and mental retardation.Hyper immunoglobulin (Ig)M,IgG deficiency,CD4 lymphopenia were common immunologic features.Variable expression can lead to death and asymptom.Penetrance can be incomplete.Hematopoietie stem cell transplantation should be taken into account for severe cases.
