There's not much beyond the motor problems in your post that is medically accurate, so please, send me links of the research you've done beyond copying a scenario from a fictional drama series. Simply from what I've read, you don't understand this disease at all. You got one symptom right, and even then it wasn't explained properly. Either that, or you've been looking at some very incorrect websites. And as the House wikia says, the Erdheim-Chester disease in the show was "fictional". If you knew that, why on earth did you use supposed facts about it that you knew were wrong?
