Our results for reference genotypes concur with previous results. CFTR function measured in organoids can be used to guide precision medicine in patients with CF, positioning organoids as a potential in vitro model to bring treatment to patients carrying rare CFTR mutations.Rescue of CFTR function with modulators measured in colon organoids can be used to guide precision medicine in patients with cystic fibrosis. Organoids are an effective model to bring treatment to patients with CF carrying rare CFTR mutations. https://bit.ly/2VHHH6s ER -
