If mitochondrial DNA is still present in a blood sample, can this blood be tested for the gene for Marfan’s syndrome? Why or why not?

    Yes, it can. But you must recall that erythrocytes have no nucleus and no mitochondrion. So, you'll have to get mitochondrial DNA from leukocytes or platelets. Blood can be easily fractionated by centrifugation, so that you get the cells you need.
