Obviously, the more responses they can get, the better the resulting data will be, and the more they can learn from it. If you'd like to participate, you can take a 40-minute online survey here: http://oregonstate.qualtrics.com/jfe/form/SV_7VEgG8kwTizenAN
If you're interested, do it now. The survey will be closing soon (possibly as early as Saturday, April 1).
Note that to be eligible for the study (and focus group), you must be 18 or older, able to communicate in English and have a rare disease or disorder (not just be the parent of someone with a rare disorder). XLH (and the related autosomal hypophosphatemias and TIO) qualify as rare disorders, since it's estimated that around 15,000 people in the United States have XLH (and the other conditions are even more rare).
And for XLHers in the UK, Spain, Italy, France, Netherlands, Germany, Denmark or Norway ONLY:
The James Lind Alliance is looking for help in identifying identify unanswered questions about XLH and two other rare disorders in adults. To share your thoughts:
The XLH Network, Inc. does not endorse or critique specific research projects, and does not counsel individual patients either for or against participation in any specific research. Prospective volunteers should always carefully review the informed consent documentation, and discuss the pros and cons of their participation with trusted advisers.
