Relapse cell population differs from acute onset clone as shown by absence of the initially activated N-ras oncogene in a patient with acute myelomonocytic leukemia.

We have conducted a follow-up study of a patient with myelomonocytic leukemia exhibiting an N-ras mutation (Gln61----Lys61) using the polymerase chain reaction method and synthetic oligonucleotide hybridization probes. This method allowed us to detect as little as 3% of N-ras-mutated cells within a population. When the patient went into clinical remission, the mutation became undetectable. When a relapse occurred, the blasts did not carry the N-ras mutation. Analysis of M13 cloned amplified N-ras sequences from relapse DNA revealed exclusively the wild type allele of the N-ras gene. These findings suggest that the relapse cell population is derived from a different clone than the acute phase population. Furthermore, the data argue that N-ras mutation is not an initiating lesion in this case of acute myelomonocytic leukemia (AMML).[1]
