Cystic fibrosis is the most common autosomal recessive disorder in Caucasian populations, with an approximate frequency of 1/2500 live births and a carrier frequency of 1/25. Due to the high rate of predicted carriers (>63,000) in the Nebraska population (1990 U.S. Census = 1,578,358), we analyzed sperm DNA obtained from semen donors at the University of Nebraska Genetic Semen Bank for eight of the more common mutations to determine the frequency and diversity in our population. The subjects included 167 semen donors (31 normal healthy donors, 56 infertility patients, 21 prevasectomy patients, and 59 prechemotherapy or preradiation cancer patients). The mutations analyzed included ΔF508, Rl17H, G542X, S549R/N, G55 1D, R553X, R560T, and W1282X. Analyses were performed using PCR amplified products that were analyzed using polyacrylamide gel electrophoresis, slot blot, and restriction endonuclease digestion. These results were correlated with results from the clinical semen analyses and selected clinical parameters. Results for the total donor population studied showed that the ΔF508 mutation was present in8/167 (4.8%) donors, the R117H mutation was present in 4/167 (2.4%) donors and the G542X mutation was present in 1/167 (0.6%) donors. The observed number of carriers from this population, 13/167 (7.8%), was significantly greater (P = 0.02) than that expected assuming a carrier frequency of 1/25. The excess of carriers was restricted to the subgroup of infertility patients. This suggests that CF carriers may be at higher risk for infertility than the general population. © 1994 Wiley‐Liss, Inc.
