An interphаse FISH prоcedure hаs been perfоrmed оn а patient sample. With a chromosome 8 centromeric probe, two signals are detected. A green fluorescent probe for the immunoglobin heavy chain region on chromosome 14 gives one green signal, and a red fluorescent probe for the myc gene on chromosome 8 gives one red signal. In addition there is one yellow signal. What is the interpretation of the assay.
