Several mutations in the thymidine kinase 2 (TK2), deoxyguanosine kinase (DGUOK), polymerase gamma (POLG) and MpV17 mitochondrial inner membrane protein (MPV17) genes have been linked to inheritable MDS in humans [5], [6], [7], [8]. This evidence concerns the gene DGUOK and myelodysplastic syndrome.
