Raccomandazioni per la diagnosi neonatale delle emoglobinopatie
Recommendations for the diagnosis of hemoglobinopathies at birth
<p>The laboratory plays an important role in the&nbsp;diagnosis of hemoglobin defects at any age. At the time of birth its role is particularly significant, considering that&nbsp;frequently the newborn has not clinical signs, even when he is carrying thalassemia or other structural defects of&nbsp;hemoglobin. The diagnostic precocity in the affected newborn will help to predict risk, determine appropriate prophylaxis&nbsp;and prevent complications. It may also be helpful for programming treatment and parent control, and planning a&nbsp;prevention for a future pregnancy. In Italy, there have been important demographic and social health changes over the&nbsp;past decade that have suggested the implementation of hemoglobinopathy screening at birth. In addition, the need to&nbsp;know the hemoglobin pattern of the cord blood for possible biobank storage should be regarded as another relevant&nbsp;target. Therefore, it seems timely to define pathways, scope and limits of a correct thalassemia diagnosis at birth through&nbsp;specific recommendations. The Italian Society of Thalassemias and Haemoglobinopathies (SITE) had already published&nbsp;recommendations for first level thalassemia diagnosis, which were primarily focused on preconceptional prevention. This&nbsp;new document provides essential guidance about laboratory methods, pre- and post analytical information flows and&nbsp;about the most appropriate approach to be followed.</p>

Identificazione e caratterizzazione di mutazioni in regioni regolatorie del gene malattia della fibrosi cistica
Identification and characterization of mutations in regulatory regions of cystic fibrosis disease gene
<p>Mutation&nbsp;epidemiology is crucial for cystic fibrosis (CF) diagnosis and counselling. ~6%-7% of alleles from CF patients do not bear&nbsp;mutations in the coding regions of the Cystic Fibrosis Transmembrane Regulator (CFTR) disease gene. In these&nbsp;patients, mutations may be present in non-coding, regulatory regions of the gene as i) intronic regions (particularly in&nbsp;high conserved sequences), ii) the promoter region or iii) the area at the 3&rsquo; of the gene, which is the target of microRNA&nbsp;regulation. We studied these regions by gene sequencing in a group of CF patients with one or both unidentified&nbsp;mutations after the analysis of CFTR coding regions, and in a group of CF patients with a different clinical expression of&nbsp;disease to evaluate if mutations in such regions may have a role in modulating CF clinical expression. Our analysis&nbsp;revealed: i) a dozen of mutations (most novel) in the large promoter area of 6000 bp at the 5&rsquo; of the gene; expression&nbsp;studies in four cell lines demonstrated that a half of such mutations may have a pathogenic effect; ii) a series of mutations&nbsp;in 52 conserved sequence tags (CSTs), i.e. intronic regions with a high homology between humans and mouse;&nbsp;expression studies revealed the pathogenic effect of one of these mutations; iii) finally, three mutations in the 1500 bp&nbsp;region at the 3&rsquo; of the gene; one of this has a pathogenic role, enhancing the interaction of CFTR with two inhibitory&nbsp;microRNAs. To the best of our knowledge, this is the first example of such pathogenic mechanism in a monogenic&nbsp;disorder. On the contrary, no mutations were identified in patients with different clinical expression in any of the three<br />non-coding regions. To conclude, the sequencing of non coding regions may improve the detection rate of molecular&nbsp;analysis in CF, but functional studies are required to define the pathogenic effect of novel mutations.</p>
