title: Atypical segregation of esterase D: evidence of a rare "silent" allele EsD0.
abstract: Electrophoretic study of esterase D in 1027 mother-child pairs showed an atypical segregation of EsD alleles in one pair. The family analysis confirmed the evidence of a 'silent' gene (EsD0), which was observed in child, mother and grandfather. R banding of the metaphasal chromosomes revealed the normal appearance of the No. 13 pair, and no deletion of homologues No. 13 was observed in this family.
