Adenylate kinase (AK), phosphoglucomutase (PGM,) and 6-phosphogluconate dehydrogenase (6PGD) polymorphisms were investigated in a sample of individuals from Central Sardinia. The gene frequencies were: AK¹ = 0.973, PGM¹₁ = 0.842 and PGD^A = 0.969. The frequencies were compared with those of other Italian populations.

A sample of the South Sardinia population was studied with respect to acid phosphatase (AcP) and esterase D (EsD) enzymes. The gene frequencies were: AcP^A = 0.326, AcP^B = 0.607, AcP^C = 0.067 and EsD¹ = 0.883. The results were compared with those of other Italian populations.
