c.2845C>T , p.His949Tyr (CFTR1) ? , The nucleotide change C->T at position 2977 (codon 949 in exon 15, H949Y), has been found in a 60 years old woman with no manifestation of gastrointestinal disease but having a bronchial dilatation. c.2846A>C , p.His949Pro (CFTR1) ? , c.2846A>T , p.His949Leu (CFTR1) ? , The nucleotide change was found by DGGE followed by sequencing of both the strands. This mutation was identified in 4 male patients from Puglia, region of Southern Italy. This mutation was identified in cis with another mutation: H939R. This is a novel complex CFTR allele: H939R + H949L. |

Do common in silico tools predict the clinical consequences of amino-acid substitutions in the CFTR gene?

Abstract [show]
Computational methods are used to predict the molecular consequences of amino-acid substitutions on the basis of evolutionary conservation or protein structure, but their utility in clinical diagnosis or prediction of disease outcome has not been well validated. We evaluated three popular computer programs, namely, PANTHER, SIFT and PolyPhen, by comparing the predicted clinical outcomes for a group of known CFTR missense mutations against the diagnosis of cystic fibrosis (CF) and clinical manifestations in cohorts of subjects with CF-disease and CFTR-related disorders carrying these mutations. Owing to poor specificity, none of tools reliably distinguished between individual mutations that confer CF disease from mutations found in subjects with a CFTR-related disorder or no disease. Prediction scores for CFTR mutations derived from PANTHER showed a significant overall statistical correlation with the spectrum of disease severity associated with mutations in the CFTR gene. In contrast, PolyPhen- and SIFT-derived scores only showed significant differences between CF-causing and non-CF variants. Current computational methods are not recommended for establishing or excluding a CF diagnosis, notably as a newborn screening strategy or in patients with equivocal test results.
