Six hundred individuals of pure Dutch ancestry have been typed for their erythrocyte phosphoglucose isomerase phenotypes by starch gel and cellulose acetate electrophoresis. In two individuals a variant phenotype was discovered. One phenotype was found to be indistinguishable from PGI-Phillips. The other variant would appear to be a new phenotype and has been designated PGI-Jager.
