CFTR and cystic fibrosis: The result of full scanning of CFTR sequences showed that a second mutation (c.3199del6 or the novel mutation c.3395insA) was associated in cis with p.I148T in all individuals with a CF phenotype, and that a third missense mutation (p.V201M) was associated in cis with complex allele [p.D1270N;p.R74W] in patients with a CBAVD phenotype in this series.
