Adenosine deaminase, adenylate kinase and acid phosphatase polymorphism in a French-Canadian population.

Adenosine deaminase (ADA), adenylate kinase (AK1), and acid phosphatase (ACP1) red blood cell enzymes were studied for allelic variation in a French-Canadian population from Quebec City, Canada. Allele frequencies in 887 unrelated individuals were for ACP1, ACP1*A: 0.305; ACP1*B: 0.635 and ACP1*C: 0.060, for ADA, ADA*1: 0.969, ADA*2: 0.031, and for AK1, AK1*1: 0.976, AK1*2: 0.024. The allele frequencies for each enzyme were identical to those previously reported in other Caucasian populations.
