Methylation profile was analyzed in 10 childhood acute lymphoblastic leukemia (ALL) and nine adult ALL cases. Four genes (p15, p16, RARbeta, FHIT) had methylation in both diseases, four genes (p14, Rb, MLH1, DAPK) showed no methylation in both diseases, and the two genes (APC, RIZ) demonstrated methylation only in adult ALL. Methylation of the RARbeta was more frequent in adult ALL than that in childhood ALL (p=0.01). The number of patients with methylation of multiple genes was higher in adult ALL than that in childhood ALL (p=0.006). Moreover, overall frequency of methylation was higher in adult ALL than that in childhood ALL (p=0.01).

The activation of genes important to acute lymphoblastic leukemia (ALL) may be evidenced by somatically acquired chromosomal translocations found recurrently in different patient subgroups. It is for this reason that research efforts have focused on the molecular dissection of recurring chromosomal rearrangements. However, even though a large number of leukemia-causing genes have been identified, the genetic basis of many ALL cases remains unknown. We and others have reasoned that novel translocations found in the leukemic cells of ALL patients may mark the location of more frequent gene rearrangements that are otherwise hidden submicroscopically within normal or complex karyotypes. Towards this end, we here describe the first reported association of a t(5;10)(q22;q24) with adult ALL. Fluorescence in situ hybridization (FISH) and Southern blot hybridization studies have eliminated likely involvement of the candidate genes APC and MCC on chromosome 5, and PAX2, TLX1, and NFKB2 on chromosome 10. Results further suggest that the breakpoint on chromosome 5 lies centromeric of APC and the chromosome 10 breakpoint is centromeric of PAX2. The genomic regions disrupted by this t(5;10)(q22;q24) have not previously been associated with leukemia.
