NCIt definition : Human DNTT wild-type allele is located within 10q23-q24 and is approximately 34 kb
in length. This allele, which encodes DNA nucleotidylexotransferase protein, plays
a role in the template direction-independent addition of deoxyribonucleotides to the
3'-hydroxyl terminus of oligonucleotide primers.;
NCIt note : The DNTT gene is expressed in a restricted population of normal and malignant pre-B
and pre-T lymphocytes during early differentiation. DNA nucleotidylexotransferase
protein is a specific marker for the diagnosis and classification of lymphoblastic
lymphoma.;
