Julie Thomson is an active mother of three grown children who has been battling PAD since her teenage years. Not a typical PAD patient, her claudication symptoms were ignored by doctors until her mid-forties when she underwent several leg bypass surgeries and was diagnosed with a newly identified rare genetic condition ACDC (Arterial Calcification due to Deficiency in CD73) by the Undiagnosed Diseases Program at the NIH. She hikes or bikes almost every day and is grateful to the doctors at UCSF and NHLBI/NIH.
