Please call the laboratory genetic counselor prior to submitting a family for linkage analysis. On at least one affected individual, we require CPK results, muscle biopsy or dystrophin analysis report and clinical history. CPK results on females seeking information on their carrier status may also be helpful.
INFORMED CONSENT from the patient is required prior to ordering a genetic test. The DNA Diagnostic Lab's consent is located on the second page of the requisition form. There is also a patient brochure, "Things Every Patient Should Know Before Consenting to a Genetic Test", available for download.
