Cosynthetase was measured in hemolysates of two patients with CEP that appeared in adulthood. The level of cosynthetase activity was found to be very low (mean 18% of normal), ruling out the hypothesis of heterozygous cases. Several obligatory heterozygous carrier were also studied in whom cosynthetase activity was found to be intermediate (mean 46.66% of normal) between the levels of normal controls and homozygous patients whereas PBG deaminase was always normal. The nature of the metabolic abnormality is undoubtedly a primary defect of the cosynthetase activity; some cases of late onset emphasize the heterogeneity of the disease.
