The delta F508 mutation in the cystic fibrosis (CF) gene was studied in a population of 18 Brazilian CF patients and their 17 families by use of PCR and differential hybridization with oligonucleotides. In a total of 34 chromosomes considered, 12 (35%) carried the F508 deletion, a frequency much lower than that reported in most other populations. As a consequence, CF in Brazil would be predominantly caused by mutations different from the F508 deletion.
通过聚合酶链反应（PCR）和寡核苷酸差异杂交技术，对18名巴西囊性纤维化（CF）患者及其17个家庭进行了CF基因突变研究。在总共34条染色体中，12条（35%）携带F508缺失突变，这一频率远低于大多数其他人群的报道。因此，巴西的CF主要由不同于F508缺失的突变引起。
