| Sample: | Adults - 3 mL whole blood in lavender top tube (EDTA) Children - 2 mL whole blood in lavender top tube (EDTA) Testing on smaller volumes than those requested will be attempted. However, in some cases, small blood volumes may compromise the ability to perform testing. Testing requires a dedicated collection tube. |

| Background: | Approximately 90% of individuals affected with FSHD have a chromosome 4q35 deletion. The identification of a characteristic 4q35 deletion is more than 90% specific for the disease. We extract DNA from peripheral blood leukocytes and digest with specific restriction enzymes. The restriction fragments are detected by Southern blot probed with p13E-11. Both pulsed field gel electrophoresis and dosage testing are performed. |
