SandraHi Cathy,
If you contact Kelly Leight with the CARES Foundation. I believe she has some information on this. She is involved in a study going on right now re: carriers and their symptoms. It would be interesting to find out what the study comes up with. I don’t remember exactly who is doing the study but I’m sure she would be able to fill you in.
I know I would like to find out more about this too!
Sandra
