Identificazionee caratterizzazione di mutazioni in regioni regolatorie del gene malattia della fibrosi cistica

Mutation epidemiology is crucial for cystic fibrosis (CF) diagnosis and counselling. ~6%-7% of alleles from CF patients do not bear mutations in the coding regions of the Cystic Fibrosis Transmembrane Regulator (CFTR) disease gene. In these patients, mutations may be present in non-coding, regulatory regions of the gene as i) intronic regions (particularly in high conserved sequences), ii) the promoter region or iii) the area at the 3’ of the gene, which is the target of microRNA regulation. We studied these regions by gene sequencing in a group of CF patients with one or both unidentified mutations after the analysis of CFTR coding regions, and in a group of CF patients with a different cl…
