We just found out me scene son also has POTS. The good news is we knew the symptoms and were able to get a diagnosis very quickly. We are confident he will overcome his symptoms as his brother was bed ridden for several months, and now, two years later, is fully functioning and just completed his first year of college. We are curious, however, if any of you have siblings or other family members who have also been diagnosed. Interesting that they have a cousin with it, and possibly an aunt as well. I haven't been able to find much information on a genetic component, so I figured I'd see what you all knew.
