If somebody (a french team preferentially) is intersted by a family with Waldenstrom macroglobulinemia, to make a study of the disease, I have my grand'pa (disease discoveredsince 1985), my father (disease discovered since 1991 apparently), my aunt (disease discovered since 1 or 2 years), and my grand'ma and my other aunt without Waldenstrom. I think it could be interesting for a team working on this disease.
