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.

status: NEW4 Confocal microscopy and biotinylation studies revealed that R1070P was not inserted into the apical membrane, R1070W was inserted at levels reduced from wild-type while R1070Q was present in the apical membrane at levels comparable to wild-type.

status: NEW192 Since R1070P was not detectable on the apical membrane of MDCK-FRT cells by biotinylation studies but was present on the membrane of nonpolarized HEK-293 cells [Mickle et al., 2000], the localization machinery for R1070P is apparently different in polarized and nonpolarized cells.

Of note, recent work has also shown that the R1070P and R1070W mutations lead, respectively, to the absence or to reduced levels of insertion of the protein into the apical membrane of polarized epithelial cells [23], suggesting that these mutations may, as DF508, affect the inter-domain interactions of CFTR.

ABCC7 p.Arg1070Pro 9401006:98:0
status: NEW99 R1070P is believed to be a disease-causing mutation as the amino acid change is nonconservative (ArgeninetoProline)inthesecondnucleotidedomain and because this amino acid is altered in two other CF mutations.Mercieretal.

The mutations R1070P and R1070Q were created directly in pRSV-CFTR, by use of a transformer site-directed mutagenesis kit (Clontech).

status: NEW68 Mutations at codon 1070 of TMD2 were selected, since two mutations (R1070P and R1070Q) have been associated with CF, whereas a third (R1070W) has been observed in men with CBAVD (table 1).

status: NEW172 B, CBAVD(R1070W)- and CF(R1070P and R1070Q)-associated mutants in TMD2 had I-V plots similar to those of wild-type CFTR: outwardly rectified currents (blackened circles) that responded to DIDS (unblackened circles) and glibenclamide (crosses).

status: NEW180 Thus, the combination of I-V relationship and response to inhibitors allowed dissection of whole-cell Cl-currents into two components: outwardly rectified and DIDS sensitive, carried by separate channels such as ORCCs; and linear, DIDS insensitive, and gli- Table 2 Summary of Processing and Whole-Cell Function of CFTR Mutants DOMAIN AND MUTATION PHENOTYPE CFTR STATUS a Processingb Function Band A Band B Band C Cl2 Channel Regulatoryc Not applicable: Wild type Normal 2 2 111 111 1 NBF1:d A455Ee CFe 1 11 2 111 1 DF508 CF 1 11 2 1 2 G551D CF 2 2 111 1 2 TMD2: R1070W CBAVD 2 1 11 111 1 R1070P CF 1 11 2 111 1 R1070Q CF 2 1 11 111 1 NBF2: D1270N CBAVD 2 2 111 111 1 G1349D CF 2 2 111 111 1 a A minus sign (2) denotes absence; a single plus sign (1) denotes "low"; a double plus sign (11) denotes "intermediate"; and a triple plus sign denotes "high."
