Recently introduced high throughput and benchtop instruments offer fully automated sequencing runs at a lower cost per base and faster assay times. Most of these variants were located in three asthma candidate genes, that is, PDE4DIP, CBLB, and KALRN. BMC Res Notes. This is due to several reasons, all of which are to do with the analysis algorithms used to detect and call bases on the sequencer. The sequence of each of these fragments is resolved simultaneously by such techniques as sequencing by synthesis. This makes the bioinformatics analyses more manageable and limits the number of variants of unknown significance (VUS) that are identified. Either way, please contact your web host immediately. SWI/SNF complex gene variations are associated with a higher NGS clinical assays have been developed for many different hematologic diseases including myeloid, lymphoid, and erythroid malignancies.7275 In addition to sequencing panels of genes, this technology has been used to sequence whole genomes, exomes (the coding exons), as well as RNA sequencing (RNAseq).7678 This technology is also being applied to the determination of epigenome modifications such as methylation that affects gene regulation and expression.79 NGS will continue to play an increasingly important role in molecular diagnostics.
