Confirmation of linkage disequilibrium between haplotype B (XV-2c, allele 1; KM-19, allele 2) and cystic fibrosis allele in the French population

Abstract

In 237 French families with cystic fibrosis (CF) restricted fragment length polymorphisms (RFLPs) were detected by two DNa probes, XV-2c and KM-19, which are tightly linked to the CF allele. As in other European populations linkage disequilibrium is found between the haplotype B (XV-2c, allele 1: KM-19, allele 2) and the CF allele. Linkage disequilibrium alters the probability that a person bearing a given haplotype is a carrier.
