GAS5

The GAS5 (growth arrest-specific transcript 5) gene can be a partner of BCL6 in diffuse large B-cell lymphoma, harboring the t(1;3)(q25;q27).

The GAS5 gene on chromosome 1q25 is the second BCL6 partner, to the SNHG5 on 6q15, which is classified as a non-protein-coding multiple snoRNA host and 5’-TOP class gene.

BCL6

The BCL6 gene is frequently disrupted at its 5’ noncoding region by 3q27 chromosomal translocations in B-cell lymphoma. As a result of translocation, BCL6 is juxtaposed to reciprocal partners, such as the immunoglobulin (Ig) gene family. Besides the Ig loci, multiple non-Ig partners of the BCL6 translocation have been reported.
