115 Other mutations (see Table 2, group b) also seem to derive from a founding event, and haplotypes differing by a single microsatellite could depend on slippage phenomena, as already proposed for mutations G85E (Claustres et al. 1996) and L1077P (Morral et al. 1996). Login to comment

85 Other haplotypes that were less commonon normal chromosomes(16-44-13, 16-35-13, 16-33-13, and 16-29-13)were each associatedwith only one CF mutation. Several mutations were associated with more than one haplotype apparentlyas the result of slippage at one of the microsatellites IVS8CA, IVS17BTA, and IVS17BCA: AF508, G542X, N1303K, R553X, Q552X, 2869insG, L1077P, 7H, and R1162X (Table 3).

0 SHORT REPORT Open Access Phenotypic expression of the p.Leu1077Pro CFTR mutation in Sicilian cystic fibrosis patients Giuseppe Fabio Parisi, Silvia Cutello, Giovanna Di Dio, Novella Rotolo, Mario La Rosa and Salvatore Leonardi* Abstract Background: The 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. Login to comment
1 Although it is typical of Southern Italy, p.Leu1077Pro is not included in the mutation panel firstly tested in individuals originated from this area. Login to comment
4 4 patients who were heterozygous for the p.Leu1077Pro mutation were included in the study. Login to comment
5 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. Login to comment
7 Conclusions: We found that the p.Leu1077Pro CFTR mutation is associated with a classic CF phenotype confirming what is reported in CFTR2 database. Login to comment
8 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.

17 The p.Leu1077Pro (L1077P) mutation consists in a transition T to C at nucleotide position 3362 in exon 17b of CFTR cDNA that is responsible of change of Leucine (CTG) to Proline (CCG) at position 1077 of the protein. This mutation belongs to the class III CFTR mutations and produce a protein that is trafficked to the cell membrane but does not respond to cAMP stimulation [8]. Login to comment
22 [8] firstly found evidence that the p.Leu1077Pro was associated with a pancreatic sufficiency even if their study did not contain functional data. Login to comment
23 The information collected in database CFTR2 [9], analyzing data from 40 patients with this mutation, lead to consider p.Leu1077Pro as a severe CF mutation, associated with PI in 78% of patients and Pseudomonas Aeruginosa infection in 55% of patients. Login to comment
25 [10] and although it should be predictive of a severe CF phenotype, p.Leu1077Pro is not included in the mutation panel firstly tested in individuals originated from this area since the information collected in CFTR2 are only available from 2011, and the only information held prior to the creation of this database were related to the work of Bozon et al.

26 The aim of our study was therefore to describe prevalence and clinical features in Sicilian patients bearing the p.Leu1077Pro CFTR mutation followed in our Cystic Fibrosis Centre to add new data on this issue. Login to comment
30 Four patients (3 males, age range 7 - 20 years) who were heterozygous for the p.Leu1077Pro mutation were included in the study: three patients also carried the p.Phe508del (ƊF508) mutation in the second allele while one carried the p.Asn1303Lys (N1303K) mutation. Login to comment
