Abstract:
Congenital leukemia occurring within 4 weeks of birth is extremely rare and, excluding transient neonatal myeloproliferation associated with Down syndrome, makes up approximately 1% of childhood leukemias. It is usually seen as acute myeloid leukemia (AML), most frequently French-American-British (FAB) types M4 and M5. Recurrent cytogenetic abnormalities have been reported in this group, and in approximately one third of cases the MLL gene at 11q23 is involved. These patients generally have a poor prognosis. We present a case of congenital leukemia (AML FAB type M1) with an acquired translocation between chromosomes 6 and 17.

Translation
Translation is the process of synthesizing proteins from the genetic information carried by messenger RNA (mRNA). Following transcription, it constitutes the final step in the expression of genes. This process is carried out by ribosomes, complexes of protein and specialized RNA molecules. Ribosomes, transfer RNA (tRNA), and other proteins produce a chain of amino acids—the polypeptide—as the end product of translation.
