Serum lipid levels and M/L55 allele distribution of HDL paraoxonase gene in Saami and Finnish men.
Paraoxonase (PON) is an antioxidative enzyme, which eliminates lipid peroxides. The mutation in codon 55 of PON1 gene causes a change of methionine (M-allele) to leucine (L-allele) and influences PON activity. The Saami are a population living in the northern part of Fennoscandia. In previous studie...
