TAL1

TAL1

A gene on chromosome 1p32 that encodes a protein which may play a key role in haematopoietic differentiation.
 
Molecular pathology
Defects in TAL1 may cause T-cell acute lymphoblastic leukaemia (T-ALL), in which there is a translocation t(1;14) (p32;q11) with T-cell receptor alpha chain (TCRA).

Numerous genes have been implicated for the pathogenesis and prognosis for T-ALL, including NOTCH1, TAL1, and HOX1 [5, 14].

These genes include TAL1 and RUNX1, both of which are essential for the development of blood stem cells, and hence to human life.
The relatively commonly occurring t(1;14)(p34;q11) translocation observed in 3% of T- ALL results in the transposition of TAL1 proto-oncogene from its normal position on chromosome 1 into the T-cell receptor (Alpha) / (standard devotions) chain complex on chromosome 14.

T-cell ALL cells undergo site-specific genetic alterations in the TAL1 gene due to problematic activity of the enzyme recombinase, and as a result, a truncated protein with oncogenic activity is produced (43).
