Abstract

Cystic fibrosis (CF) is the most common autosomal recessive disorder in Caucasian populations with an approximate frequency of one in 2,500 live births and a carrier frequency of one in 25. We studied 400 individuals seen at The Nebraska Regional Cystic Fibrosis Center that included 139 CF patients, 206 parents, and 55 unaffected siblings to determine the frequency of the ΔF508, R117H, G542X, S549R/N, G551D, R553X, R560T, and W1282X mutations. In addition, we determined haplotypes on each of these individual's chromosomes using four markers that included XV‐2c, KM‐19, pMP6d.9, and G2. Results from this study showed that the ΔF508 mutation was present in 70% of CF chromosomes. Of the 139 CF patients 74 (53%) were homozygous for the ΔF508 deletion, 47 (34%) were heterozygous for the ΔF508 deletion and an unknown mutation, and 18 (13%) carried two unknown mutations. Four additional‐mutations were also found in our population and included G542X (6%), G551D (5%), R553X (4%), and R560T (1%). One patient was documented to be a compound heterozygote for G542X/G551D. A polymorphism, F508C, that has previously been reported in several families was also present in our study. The most common haplotype associated with the ΔF508 deletion in our CF patients was the E haplotype (CF Consortium B) while other mutations were associated with a variety of haplotypes. © 1993 Wiley‐Liss, Inc.
