Identity

ICD-Topo C420,C421,C424 BLOOD, BONE MARROW, & HEMATOPOIETIC SYS
ICD-Morpho 9837/3 T lymphoblastic leukaemia/lymphoma
Atlas_Id 1141

Clinics and Pathology

Disease T cell acute lymphocytic leukaemia (T-ALL)
Clinics yet poorly known: only 1 case: a young adult male patient with high WBC (common features in T-ALL); bone marrow transplantation; complete remission: 43 mths +

Genes involved and Proteins

Gene NameTAL1 (T-cell acute leukemia 1)
Location 1p33
Dna / Rna complex alternate splicing
Protein contains a basic Helix-Loop-Helix (DNA binding) domain; forms heterodimers; transcription factor; role in haematopoietic cell differentiation
Gene Nameyet unknown gene
Location 5q31

Result of the chromosomal anomaly

Hybrid gene
Description breakpoint on TAL1 was found 10kb upstream the gene, as was found in the cases of t(1;3)(p32;p21), while it is more 3', within the gene, in the t(1;14)(p32;q11) and in TAL1 deletions.
  
Fusion Protein
Expression Localisation high nuclear expression
  

To be noted

Additional cases are needed to delineate the epidemiology of this rare entity:
