People with Cystic Fibrosis have a couple of missing base pairs in a gene. When expressed the aa-chain is different and the folding results in a different structure which alters the proteins function. In my opinion the elucidation of the folding steps might lead to a treatment. So in theory research in this area might be very useful.
Don’t know of a Boinc project that is carrying out such CF research however. Rosetta and Folding@home do research in this general area (folding) but I don’t know if they are presently doing any work directly on CF. Foldit might have done some work, or not, but that’s a hands on game like tool, not like Boinc. I suggest you ask at these projects.
Good luck,
