Summary
In a survey of serum pseudocholinesterase levels and variants in the peoples of Papua-New Guinea (2144 individuals studied) it was found that the frequency for the atypical cholinesterase gene as determined by dibucaine inhibition ranged from 0.004ā0.015. No homozygotes for the atypical cholinesterase were found. No individuals were found with extremely low or zero enzyme levels.
Considerable variation was observed in serum pseudocholinesterase level between the sexes and the various age groups in the populations studied, although variation between the highland and coastal regions was less than the variation within the regions.
In groups where poor nutrition and malaria might be expected to cause liver damage the levels were lower than in well-fed malaria-free controls, although previous studies had not shown a significant difference between the Ī³-globulin level of the two groups.
It was concluded that these results added weight to the view that high Ī³-globulin levels in New Guinea were primarily a result of infection and not of liver damage.
