1 Indeed, knowing that the molecular basis of cystic fibrosis (CF) is highly heterogeneous in our population, the study of haplotype association with normal and CF chromosomes could be very helpful in cases where one or both mutations remain unidentified. In this study, we analysed with PCR-RFLP and capillary electrophoresis some extra (pJ3.11, KM19 and XV2C) and intragenic (IVS8CA, IVS17bTA and IVS17bCA) polymorphic markers in 50 normal and 10 Tunisian patients carrying the rare E1104X mutation in order to determine the haplotype associated with this mutation.

14 The haplotypes associated with the CFTR mutations in the North African population remain unidentified. In this work we aimed to determine haplotypes associated with the E1104X mutation using 3 intragenic microsatellites (IVS8CA, IVS17bTA and IVS17bCA), and 3 extragenic markers (pJ3.11, KM19 and XV2C).

43 Results and Discussion The E1104X mutation, initially discovered by Zielenski in a French-Canadian patient in 1992 (http://www.genet.sickkids.on.ca/cftr/), consists of a single nucleotide substitution (G to T) at position 3442 in exon 17b, and causes introduction of a premature stop codon (GAA to TAA) at position 1104 in the protein sequence (27).

64 However, the haplotype analysis linked to rare mutation remains undetermined, that is why in this study we aimed to determine haplotypes associated with the E1104X mutation using some extra (pJ3.11, KM19 and XV2C) and intragenic (IVS8CA, IVS17bTAand IVS17bCA) polymorphic markers.

97 The second mutation has been identified in association with E1104X mutation in a patient from Southern Tunisia (Zarzis), this leads to a premature stop codon 31 nucleotides downstream the deletion/insertion. Login to comment

106 Genotype analysis We identified five CF mutations in our cohort: F508del mutation (63.20%), which is the most frequent mutation N1303K (4.4%), G542X (2.94%), E1104X (2.94%) and 1524 + 5insC (1.47%) utilizing the obtained data from previously carried out molecular study using different techniques (DGGE, DHPLC and sequencing) [7].
