Phenotypic expression of the p.Leu1077Pro CFTR mutation in Sicilian cystic fibrosis patients.
Article in BMC research notes, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers, 1 of them a synthesis that pooled it.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThe p.Leu1077Pro CFTR mutation was firstly described in 1992 as a mild allele that confers a pancreatic sufficiency phenotype but the information collected in database CFTR2 lead to consider p.Leu1077Pro as a severe CF mutation. Although it is typical of Southern Italy, p.Leu1077Pro is not included in the mutation panel firstly tested in individuals originated from this area. The aim of our study was to describe prevalence and clinical features in patients bearing this mutation followed in our Cystic Fibrosis Centre to demonstrate that this mutation should be included in the mutation panel firstly tested in patients originated from Southern Italy.
findingsWe reviewed data from a cohort of 111 cystic fibrosis patients. 4 patients who were heterozygous for the p.Leu1077Pro mutation were included in the study.In our Cystic Fibrosis Centre, the prevalence of p.Leu1077Pro is 3.6% among all mutations. All patients had positive sweat test values, pancreatic insufficiency and pulmonary exacerbations. One out of four patients even showed both FEV1 and FVC values significantly below the normal range, the presence of bronchiectasis and chronic Pseudomonas aeruginosa colonization.
conclusionsWe found that the p.Leu1077Pro CFTR mutation is associated with a classic CF phenotype confirming what is reported in CFTR2 database. The relatively high prevalence of p.Leu1077Pro associated with the severe clinical course of the disease in patients bearing this mutation is of interest for genetic counselling purposes, as it should be part of mutation panel to be tested in individuals originated from Southern Italy.
