Genes affected

DNTT (HGNC:2983): (DNA nucleotidylexotransferase) This gene is a member of the DNA polymerase type-X family and encodes a template-independent DNA polymerase that catalyzes the addition of deoxynucleotides to the 3'-hydroxyl terminus of oligonucleotide primers. In vivo, the encoded protein is expressed in a restricted population of normal and malignant pre-B and pre-T lymphocytes during early differentiation, where it generates antigen receptor diversity by synthesizing non-germ line elements (N-regions) at the junctions of rearranged Ig heavy chain and T cell receptor gene segments. Alternatively spliced transcript variants encoding different isoforms of this gene have been described. [provided by RefSeq, Jul 2008]

Nov 18, 2022

The c.419C>G (p.P140R) alteration is located in exon 3 (coding exon 3) of the DNTT gene. This alteration results from a C to G substitution at nucleotide position 419, causing the proline (P) at amino acid position 140 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
