I have a friend who according to Shoemaker has biotoxin illness: pathway compromised (VIP, MSH, c4a extremely elevated, etc) BUT no suseptable gene.. she is 17-3-52b not 52a. We have checked and double checked her numbers. I have seen here http://esme-eu.com/getfile.php/Files/de Meirleir, K., poster for XMRV workshop(1).pdf that c4a can be high with xmrv (which she has not been tested for). Is it possible that XMRV can cause the entire biotoxin pathway to be compromised and this look like "biotoxin illness" when it is not? Thank you!
