In the 100-year period 1880-1980 the Hutterite population increased from about 442 to 23,000 individuals in North America. There are three endogamous subdivisions in this Caucasian genetic isolate. A total of 11 cystic fibrosis (CF) families from Canada and the United States were investigated, including at least two families from each of the three subdivisions, the Dariusleut, Lehrerleut, and Schmiedeleut. A study of RFLPs for the loci D7S8, D7S23, MET, and D7S18 (also called D7S16) in the region of the CF gene in 10 families shows considerable genetic variability. There were three different extended CF gene-region haplotypes on CF chromosomes (CF haplotypes), and there were 13 different extended CF gene-region haplotypes on normal chromosomes (normal haplotypes). The three CF haplotypes have different D7S23 and MET haplotypes. Parents who have the same CF haplotype are, on the average, more closely related than parents who have different haplotypes, but only within the same subdivision. A marriage node graph of 11 families illustrates the complexity of Hutterite genealogies. The frequency distribution of CF haplotypes in the Hutterite sample differs notably from those of larger agglomerates of family data from collaborative studies, with respect to D7S8, MET haplotypes, and D7S23 haplotypes. We propose that there were at least three CF carriers among the founders of the Hutterite population and that copies of a particular CF haplotype in current individuals are identical by descent. The alternative that one or more genetically distinguishable CF haplotypes resulted from recombination since the founding of the population is considered to be less likely.
