I have just been found to have MGUS, after asking my PCP for recommendations after 60 year old niece diagnosed with multiple myeloma and my sister having had it in 1991 and dying 3 years later (which was the norm then.) My question is do any of you with MGUS or MM have other family members who have been similarly diagnosed? Supposedly both are non-hereditary, but I am questioning that. We are all female and white, not what supposedly typical patient with MM is.
