My sister has Fragile X. Is there ever going to be a cure?
     Donna Krasnewich, M.D., Ph.D.: Investigating diseases resulting from abnormal metabolism of carbohydrates. Fragile X is due to expansions or changes in a specific area of the X chromosome. These expansions are carried by all of the cells of the body. You can imagine that it would be very hard to change the DNA/chromosomes in each and every cell. Because of this there is likely not going to be a cure for Fragile X. What is very important for your sister and your family is that she is in a great learning environment and has the opportunity to adapt and grow to be the best that she can be. Your question is a good one and it might be useful to you and your family to talk to a geneticist who is has special knowledge Fragile X. You can find a geneticist near you using the link at the National Society of Genetic Counselors http://www.nsgc.org/resourcelink.cfm. Keep asking these very thoughtful questions.
