Abstract：
:The myelodysplastic syndrome is a paradigm of human preleukaemia. Normal haemopoiesis is progressively displaced by an abnormal clone derived from a mutated stem cell. The initial mutation is unknown but its occurrence may be related to the overall load of random mutations which are a consequence of both intrinsic DNA defects and external mutagens. Evolution of the pathological population is marked by an increasing load of genetic lesions at the molecular and cytogenetic levels. Ras mutations can be detected in the blood of about 50% of MDS patients. Fms mutations are less common but these lesions can be found both in patients and in haematologically normal subjects who have previously received cytotoxic therapy suggesting that they can occur early in the preleukaemic process. Clonal haemopoiesis in the absence of either ras or fms mutations can occur in these subjects. The data suggest the inability of mutant ras or fms genes alone to produce observable preleukaemic changes but that subjects with these mutations may be predisposed to future MDS. Ras mutations are a common accompaniment of a wide variety of malignancies and experimental transfection of the mutant gene can induce a malignant phenotype in cultured cells. There are many possible mechanisms for this transformation which may be relevant in a clinical context. Experimentally observed effects include a direct influence on the cell cycle, the induction of drug resistance and the stimulation of autocrine growth factor production. It may eventually be possible to define which gene mutations are important in conferring a malignant state, which determine phenotype and which are of incidental significance.
