This study compared the efficacy of single\u2010strand conformation polymorphism analysis (SSCP) and high\u2010performance liquid chromatography under partially denaturing conditions (dHPLC) for screening mutations in CGD patients. We selected 10 male CGD patients with a clinical history of severe recurrent infections and abnormal respiratory burst function. gDNA, mRNA and cDNA samples were prepared by standard methods. <jats:italic>CYBB<\/jats:italic> exons were amplified by PCR and screened by SSCP or dHPLC. Abnormal DNA fragments were sequenced to reveal the nature of the mutations. The SSCP and dHPLC methods showed DNA abnormalities, respectively, in 55% and 100% of the cases. Sequencing of the abnormal DNA samples confirmed mutations in all cases. Four novel mutations in <jats:italic>CYBB<\/jats:italic> were identified which were picked up only by the dHPLC screening (c.904 insC, c.141+5 g&gt;t, c.553 T&gt;C, and c.665 A&gt;T). This work highlights the relevance of dHPLC, a sensitive, fast, reliable and cost\u2010effective method for screening mutations in CGD, which in combination with functional assays assessing the phagocyte respiratory burst will contribute to expedite the definitive diagnosis of X\u2010linked CGD, direct treatment, genetic counselling and to have a clear assumption of the prognosis. This strategy is especially suitable for developing countries.<\/jats:p>","DOI":"10.1111\/j.1365-3083.2012.02714.x","type":"journal-article","created":{"date-parts":[[2012,4,30]],"date-time":"2012-04-30T05:46:33Z","timestamp":1335764793000},"page":"158-166","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["High\u2010Performance Liquid Chromatography Under Partially Denaturing Conditions (dHPLC) is a Fast and Cost\u2010Effective Method for Screening Molecular Defects: Four Novel Mutations Found in X\u2010Linked Chronic Granulomatous Disease"],"prefix":"10.1111","volume":"76","author":[{"given":"E.
