@IndianaScott, I have a form of cerebral angiopathy sometimes called "disappearing White Matter". It is diagnosed as a portion of my Gelsolin, or AKA Finnish Amyloidosis. It is a rare one, something around 1 of every 2,000,000 physician visits results in the dX. Every person I can find who is diagnosed with FKTN (Fukutin Limb Girdle Muscular Dystrophy- LGGMD-4) who has been tested for Amyloid also also has Gelsolin. Including me, and about 100 others around the world. So the CA might occasionally be a bit mis-diagnosed as only from Gelsolin (GSN - OMIM: 105120 or 137350)
