Hi friends
Do you have any update on this question about how to detect the
dysferlin in the blood? I have a nephew that had a problem of MD and
we are trying to identify which one is. Also, do you know if exist in
the market any product or vitamin suplement that contain the
dysferlin and if it is something that he can take and it could work
in that way? Or is this a lot more complicated than this?
Also, Im trying to find what are the best place to check him in USA,
he is living in Peru right now and is only 3 years old, but he have
it since 2 years, which is odd really.
Thank you,
Raul
