Mutations of the arginine residue at codon 1070 have been associated with different disease consequences; R1070P and R1070Q with "severe" pancreatic insufficient cystic fibrosis (CF) and R1070W with "mild" pancreatic sufficient CF or congenital bilateral absence of the vas deferens.

There are two other sequence variations in the CFTR gene; one of them (129G----C) is located 4 nucleotides upstream of the proposed translation initiation codon and, although present only on CF chromosomes, it is not clear whether it is a disease-causing mutation; the other (R75Q) is most likely a sequence variation within the coding region.

Deletion of Phe<sup>508</sup> (ΔF508), the most prevalent mutation in CF, and other mutations in CFTR that impair its trafficking, such as N1303K, also led to quantitative and qualitative PTM changes that prevented the maturation of misfolded CFTR.

We have used this stabilized background to study the effects of NBD2 mutations identified in cystic fibrosis (CF) patients, demonstrating that mutants such as N1303K and G1349D are characterized by lower stability, as shown previously for some NBD1 mutations, suggesting a potential role for NBD2 instability in the pathology of CF.

Options for pharmacological correction of CFTR-p.Phe508del (F508del) are being extensively studied but correction of other trafficking mutants that may also benefit from corrector treatment remains largely unknown.We studied correction of the folding mutants CFTR-p.Phe508del, -p.Ala455Glu (A455E) and -p.Asn1303Lys (N1303K) by VX-809 and 18 other correctors (C1-C18) using a functional CFTR assay in human intestinal CF organoids.Function of both CFTR-p.Phe508del and -p.Ala455Glu was enhanced by a variety of correctors but no residual or corrector-induced activity was associated with CFTR-p.Asn1303Lys.
