Remarks

Diagnosed at age 6 on basis of abnormal stools, persistent cough and rales, weight loss, and positive sweat test; on Pancrease, bronchodilators, and intermit antibiotics; 50-75 percentile for height and weight; similarly affected brother; donor subject is a compound heterozygote: one allele carries the deltaF508 deletion mutation (PHE508DEL) and a second allele carries a C-to-T substitution at nucleotide 1789 (1789C>T) which converts the arg-553 codon (CGA) to a stop codon (TGA), resulting in a nonsense mutation in exon 11 in the CFTR gene [ARG553TER (R553X)]
