Diagnosi molecolare di primo livello nella fibrosi cistica: confronto tra tre metodiche commerciali
First-level molecular diagnosis of cystic fibrosis (CF): comparison of three commercial procedures
<p>CF is one&nbsp;of the most common life-threatening autosomal recessive disorders among Caucasians. To provide an useful CF test&nbsp;and improve the detection rate of CF mutation in the general population, the selection of a mutation panel should be&nbsp;considered for covering the population disease risk. The aim of this study was to evaluate and to compare the&nbsp;performance of 3 different analytical CF molecular assays: INNO-LiPA, NanoChip CF70 and xTAG Cystic Fibrosis.&nbsp;All 3 mutation panels showed a good detection rate in our geographical area. We analyzed 100 DNA samples with&nbsp;INNO-LiPA and NanoChip CF70; half of those samples were also analyzed with xTAG Cystic Fibrosis. All tests&nbsp;included the most frequent CF mutations along with Poly-T screening. As some discordant results were found, some&nbsp;samples were also analyzed by CFTR massive parallel sequencing (MPS) with MASTR v2 assay (Multiplicom) run&nbsp;on 454 GS Junior. INNO-LiPA and NanoChip were concordant for 99 out of 100 samples. Only one, carrying the&nbsp;852del22 mutation, resulted as discordant: MPS confirmed the &ldquo;wild type&rdquo; genotype previously obtained by&nbsp;NanoCHIP. On the contrary, in a sample genotyped by both INNO-LiPA and MPS as compound heterozygote (3272-&nbsp;26 A/G; 621+3 A/G), NanoChip only detected the 3272-26 A/G mutation. Finally, 47 out of 50 samples were correctly&nbsp;genotyped by xTAG Cystic Fibrosis.</p>
