In Burkitt's Lymphoma, IGH is most notably involved in rearrangements involving the MYC oncogene as a result of the t(8;14)(q24.21;q32.33) translocation1. However, other rearrangements of the IGH gene are also seen in a number of different malignancies, including T-ALL, Chronic Lymphocytic Leukaemia (CLL) and Acute Lymphpblastic Leukaemia (ALL). There are a number of stereotypical translocations involved in each of the diseases and more are being described regularly.

In T-ALL for example, IGH is observed in the t(14;14)(q11;q32) translocation (or inv(14)(q11q32) rearrangement)2 that is found in T-cell leukaemia associated with ataxia-telangiectasia (AT). However, rare reports have indicated that this abnormality also occurs in B-ALL. The recurrent t(14;19)(q32;q13) translocation associated with chronic B-cell lymphoproliferative disorders, such as atypical CLL, has also been shown to occur in B-ALL and results in the juxtaposition of the IGH and BCL3 genes and subsequent over expression of BCL33. More recently, a report suggested the involvement of IGH in a novel cryptic translocation in paediatric T-ALL, which also involved TLX3 (HOX11L2) or NKX2-5 (CSX) on 5q35 brought about by a t(5;14)(q35;q32) translocation4. IGH is involved in a large number of different rearrangements with fusion partners on almost every other chromosome. Many of these rearrangements have been reported in only one or a few cases but some are more common, such as IGH/BCL2, caused by the t(14;18) translocation5, and IGH/CCND1, a result of the t(11;14) translocation6. All these rearrangements do, however, have breakpoints within the IGH gene. We have designed a split probe set for IGH, which allows the detection of rearrangements, regardless of the partner gene involved.
