A study by Zanetto et al studied 5 cases of CD10+ MCL expressing BCL6 protein and found that 1 case carried a BCL6 translocation and 3 others had extra copies of the BCL6 gene, suggesting the BCL6 protein expression found in these cases could be the result of chromosomal alterations involving BCL6, rather than resulting from a germinal center origin of the lymphoma. Here, MME is linked to lymphoma.
