Genetic Linkage Studies of Transf errin, Pseudocholinesterase, and Chromosome 1 Loci

Abstract
Genetic linkage analysis of a pedigree with four different alleles for pseudocholinesterase (CHEl) gives a positive lod score of 0.37 at Θ= 0.16 for linkage with transferrin (TF), a finding which supports previous reports of linkage between CHEl and TF. Evaluation of linkage relations of CHEl and TF using unreported families from our data bank fails to establish linkage with chromosome 1 loci (6-PGD, Rh, PGM1, AMY2 and FY). These results are consistent with recent studies which suggest that TF is on human chromosome 3.
