[Frequency of genes corresponding to adenosine deaminase, 6-phosphogluconate dehydrogenase and esterase D...

The frequencies of the genes expressing the variation of erythrocytic enzymes ADA, 6PGD and esterase D have been estimated in Paris population. These results are as follows: (formula see text). These are compared to those of other european populations. Although ADA shows the lowest frequency in the french population, the distribution is not significantly different from the whole european distribution. No difference is noticeable for 6PGD and esterase D.
