Abstract
G6PD activity was determined in liver biopsy specimens from 31 patients (25 men and six women). The G6PD genotype of the patients was determined by carrying out on lysates of their red blood cells quantitative assays of the enzyme and starch-gel electrophoresis. In 21 subjects with normal G6PD activity in red cells, a relatively wide variation of G6PD activity was found in liver extracts. By contrast, in 10 subjects with G6PD deficiency, the activity of the enzyme in liver extracts was always low. The difference between the distribution of liver G6PD activity values of G6PD-normal and G6PD-deficient subjects was statistically significant (p less than 0.01). We conclude that G6PD deficiency of the African type is also expressed in the liver. These findings may have a bearing on hyperibilirubinemia, which cannot be entirely attributed to hemolysis, often encountered in G6PD-deficient patients.
