  We present on a new case of myelodysplastic syndrome characterized by array Comparative Genomic Hybridization. This technique confirmed the monosomy 7, detected by conventional cytogenetics, and revealed also a deletion on the short arm of chromosome 12. This deletion extends for about 14.8 Mb and breaks ETV6 gene. 12p deletion extents in hematological malignancies may vary, but the minimally deleted region almost invariably contains ETV6, that is considered the main candidate tumor suppressor genes within the region for tumor progression. It has been shown that levels of ETV6 were significantly decreased in cases with 12p13 deletions, whereas expression of other genes in the deleted region, like BCL2L14, LRP6, DUSP16 and GPRC5D, did not show any variation, independently of their copy number status. This observation strengthens the fact that ETV6 may play a potential role in.. View More»
