title: Esterase D polymorphism in a French-Canadian population.
abstract: Red blood cell esterase D (ESD) polymorphism was studied in a French-Canadian population from Quebec city, Canada, by means of high voltage electrophoresis on agarose gel followed, in heterozygotes for ESD 1, by IEF to reveal the possible allele ESD*5. Frequencies of the ESD alleles in 904 unrelated individuals were ESD*1: 0.888, EDS*2: 0.095 and ESD*5: 0.017. The segregation pattern observed in 275 families confirmed a Mendelian inheritance of three autosomal alleles.
