To investigate whether MNX1 may interact with the CDK6 locus in selected del(7)(q22q36) samples, we performed circular chromosome conformation capture (4C) using a 5′ part of MNX1 as viewpoint in two primary AML samples (2KFQ and MTM9) and one human PDX (AML-661) with del(7q). Here, MNX1 is linked to acute myeloid leukemia.
