Hi everyone. It is very important that every GAN patient have gene sequencing / mutation analysis done. There are two doctors that perform this, Dr. Flanigan in Utah, USA and Dr. Houldon in London, England. This is a blood test that can be drawn by your local care provider and sent to their labs. Each of the physicians can send the instructions for the process of drawing the blood (what color vial, how much, packing, shipping, etc.) This can take some time, up to 12 weeks. We need to be sure that we each have this done, as it tells researchers about the particular mutation. Please contact Hannah's Hope Fund for contact information for these doctors.
