Preferred Label : Immunodeficiency due to purine nucleoside phosphorylase deficiency;
ICD-11 definition : Purine nucleoside phosphorylase deficiency is a purine metabolism disorder resulting
in combined T and B cell immunodeficiency that results in recurrent infections. Children
are particularly prone to viral infections (chicken pox, mumps, cytomegalovirus) and
vaccines, but suppurant bacterial infections have also been noted. One third of all
patients have anemia, and 2/3 have neurological signs (ataxia, spastic tetraplegy
and tremor).;
ICD-11 synonym : deficiency of inosine phosphorylase; NP deficiency; PNP deficiency; deficiency of purine-nucleoside phosphorylase; NP - [nucleoside phosphorylase] deficiency; Nucleoside phosphorylase deficiency; PNP - [purine nucleoside phosphorylase] deficiency;
