SUMMARY One hundred and two parents of children with cystic fibrosis and 52 control parents were studied with regard to physical examination of the chest, personal and family history, sweat electrolytes and pulmonary function tests. The physical examination of the chest was negative in all parents. When the C.F. parents were compared with the control group, no significant differences could be found in the personal and family histories of chronic cough, allergy, gastrointestinal disorders (ulcer and cholelithiasis) and diabetes. The concentration of sodium, chloride, and potassium in the sweat (produced by iontophoresis) was similar in the two groups of parents. The pulmonary function tests (vital capacity, timed vital capacity, peak expiratory flow rate, maximal breathing capacity, and nitrogen washout) showed no significant differences between the two groups of parents. This study provides no evidence that cystic fibrosis is inherited as a dominant disease. By the methods used no particular characteristics were found which could differentiate the heterozygote carrier of cystic fibrosis from the non‐carrier.
