NCIt definition : Human ITPA wild-type allele is located in the vicinity of 20p13 and is approximately
23 kb in length. This allele, which encodes inosine triphosphate pyrophosphatase protein,
is involved in the dephosphorylation of non-canonical purine nucleotide triphosphates.
Mutation of the gene is associated with inosine triphosphatase deficiency and developmental
and epileptic encephalopathy 35.;
