A combination of several enzymes, RNase-T1, nuclease S1, T4-polynucleotide kinase and T4-RNA ligase were used to prepare and modify different fragments of yeast tRNAAsp (normal anticodon G U C). This allowed us to reconstitute, in vitro, a chimeric tRNA that has any of the four bases G, A, U or C, as the first anticodon nucleotide, labelled with (32p) in its 3' position. Such reconstituted (32p...

Case Details. We report rare familial unbalanced translocation of chromosomes 7 and 12, which was diagnosed prenatally at 20+3 weeks of gestation. Woman's partner had been tested in the past and was found to be a carrier of a balanced translocation; his karyotype showed a balanced reciprocal translocation of 46, XY, t(7;12)(q34;q24,32). Partner's brother had an unbalanced form of the translocat...

The RCSD1 gene has recently been identified as a novel gene fusion partner of the ABL1 gene in cases of B-cell Acute Lymphoblastic Leukemia (B-ALL). The RCSD1 gene is located at 1q23 and ABL1 is located at 9q34, so that the RCSD1-ABL1 fusion typically arises through a rare reciprocal translocation t(1;9)(q23;q34). Only a small number of RCSD1-ABL1 positive cases of B-ALL have been described in ...

We examined a girl presenting neuropsychomotor developmental delay and multiple malformations including antenatal and postnatal growth retardation, congenital heart defect, and facial dysmorphisms. Cytogenetic analysis was performed on peripheral blood lymphocytes with the GTG-banding technique, which revealed an unbalanced translocation: 46,XX,der(13)(13pter→13q34::3p24→3pter)pat. Karyotype an...

The t(9;22)(q34;q11.2) translocation results in a BCR-ABL1 fusion gene located on the Philadelphia chromosome (Ph), causing a constitutively active BCR-ABL1 tyrosine kinase. This fusion gene is found in virtually all cases of CML, 5% of pediatric and 15-30% of adult cases of ALL, and 1-2% of cases of de novo AML [1-3]. While mixed phenotype acute leukemia (MPAL) with t(9;22)(q34;q11.2) is rare,...
