Generation of an induced pluripotent stem cell line (IGGi002A) from nasal cells of a cystic fibrosis patient homozygous for the G542X-CFTR mutation

Abstract

Cystic Fibrosis Transmembrane conductance Regulator (CFTR) is a chloride channel defective in cystic fibrosis (CF). Several CFTR mutations are causative of CF, among which G542X is a nonsense mutation introducing a premature stop codon which prevents CFTR protein synthesis. We generated a new iPSC line from nasal cells carrying G542X homozygous mutation for CFTR: IGGi002A. This cell line has normal female karyotype, express pluripotency markers and could differentiate into three germ layers in vitro. This iPSC line may be used for disease modeling (cell differentiation and organoid formation) and development of personalized treatments by genome editing or pharmacological screening.
