Madam Chair, I would defer on that question to my colleague, Dr. Wong-Rieger.
I will answer, though, that some of it is hard to measure. It will be inexact because diagnosing some of these diseases is very hard to do. We may not be picking up every patient in the country. But we think there are just under 7,000 diseases that have been identified internationally. How many Canadians have them? Again, there's not a specific count, but we do think, as I mentioned in my opening remarks, that there's reason to believe that one out of 10 Canadians is affected by a rare disease.
I don't know if Dr. Wong-Rieger would have more exact statistics on that.
