Classification of AA and EA patients by MM subtype using aCGH. Penetrance plots are shown depicting chromosome gains (red) and losses (green) from the analysis of tumor DNA from MM patients. Data were visualized using DNA Analytics software (Agilent). Patients were grouped by race and stratified into the 2 major subtypes, H-MM and NH-MM. Subtype frequencies were compared between the 2 groups: (A) AA H-MM (53%), (B) AA NH-MM (47%), (C) EA H-MM (53%), and (D) EA NH-MM (47%).
