Sunday 16 September 2007

The t(7;12)(q36;p13) is a recurrent translocation involving the ETV6 (TEL) gene at 12p13 and a heterogeneous breakpoint at 7q36.

A fusion transcript between HLXB9 and ETV6 in AML with t(7;12) is occasionally found.

The t(7;12) is almost exclusively present in infant AML and covers 30% of infant AML, while it is extremely rare in infant ALL and older children. (16646086)

The t(7;12) is associated with a poor outcome and an ectopic expression of HLXB9 is commonly involved in this genetic subtype of leukemia. (16646086)
