Thymidine Kinase 2 Deficiency - Symptoms, Causes, Treatment
WEBSep 14, 2022 · TK2D is caused by pathogenic variants (mutations) in the thymidine kinase 2 (TK2) gene. This gene makes a protein known as thymidine kinase 2, which helps make certain types of nucleotides which are the building blocks for DNA needed to maintain mitochondrial DNA.
