title: Aberrant protein pattern in red cell membranes of a patient with mild hemolytic anemia.
abstract: A 17-year-old patient with mild hemolytic anemia known since early childhood displayed an aberrant protein pattern of his red cell membranes when analyzed in SDS-polyacrylamide gel electrophoresis (SDS-PAGE). A double protein band in the low molecular weight region (molecular weight of about 33,000) was distinctly reduced or missing in the membranes that were investigated concomitantly with those of controls on two occasions at an interval of 6 months'. The phosphorylation pattern of membrane phosphoproteins, on the other hand, did not seem to differ from that of controls. It is suggested that a causal relationship existed between the observed membrane abnormality and the mild hemolytic anemia.
