ABSTRACT

A sample of 689 blood donors was analysed with the aim of searching for an influence of the CHE2 locus of serum cholinesterase on adult weight. A frequency of 6.82% of the CHE2 C5 + phenotype was observed. The data showed that the distribution of weight is positively correlated with that of serum cholinesterase activity in one phenotype (CHE2 C5-) and independent of it in the other (CHE2 C5+).

Keywords: CHE2 locus; Cholinesterase; Brazil.
