[Familial bisalbuminemia].

Bisalbuminemia is characterized by two albumin peaks in the electrophoresis of serum. There are different forms of bisalbuminemia: inherited and acquired. The acquired form is mainly transitory, whereas the familial form is permanent. The frequency of bisalbuminemia in the general population has been reported to be between 0.0003 and 0.01%. This paper presents a case of familial bisalbuminemia as well as the family tree-to the extent obtainable. A married couple, in which the husband had bisalbuminemia, had seven children and 18 grandchildren. Bisalbuminemia was also found in two children and in two grandchildren.
