The esterase D polymorphism in patients with diabetes or carcinoma of the bladder and a matched sample of non-donor controls.

Results are reported for the Esterase D polymorphism in a sample of the general population from the Durham area. Gene frequencies agree well with those previously reported from the north of England. No differences are revealed when the sample is subdivided on the basis of age. No significant differences are observed between this sample and two disease series from the same region, one with diabetes, the other with carcinoma of the bladder. This holds true when the disease groups are considered with regard to current age, age at diagnosis, and in the case of the diabetic, current treatment.
