[Hereditary bisalbuminemia. Study of a new familial case in France (author's transl)].

A case of bisalbuminemia of slow type was discovered in a 41 year old woman with obesity, diabetes mellitus and hypertension. This abnormality was discovered in six other members of the family and was thus hereditary. After a description of the laboratory tests used, the various forms of bisalbuminemia are described together with the circumstances of onset of the acquired forms, the biochemical and metabolic characteristics of the hereditary forms and their mode of transmission. Bisalbumin is present in all races. The mother of our case was of Italian origin, which permitted us to classify this case with others of Italian origin.
