MRNA expression profiling in patients with Tetralogy of Fallot and healthy unaffected individuals


ABSTRACT: Right ventricular mRNA profiles from 22 patients with Tetralogy of Fallot (TOF) and mRNA-seq profiles from the left and right ventricle (LV and RV, respectively) of 4 healthy unaffected individuals (NH) were generated. The total RNA was isolated from the 30 human heart samples using TRIzol. mRNAs were isolated from total RNA and prepared for sequencing using Illumina Kit RS-100-0801 according to the manufacturer's protocol (Preparing Samples for Sequencing of mRNA Sept 2008). The sequencing libraries were generated using a non-strand-specific library construction method. The purified DNA fragments were used directly for cluster generation, and 36 cycles of single-end read sequencing were performed using the Illumina Genome Analyzer. Sequencing reads were extracted from the image files using the open source Firecrest and Bustard applications (Illumina Genome Analyzer pipeline 1.3.2, 1.4.0 and 1.5.0).

Tetralogy of Fallot (TOF) is the most common cyanotic congenital heart disease. Its genetic basis is demonstrated by an increased recurrence risk in siblings and familial cases. However, the majority of TOF are sporadic, isolated cases of undefined origin and it had been postulated that rare and private autosomal variations in concert define its genetic basis. To elucidate this hypothesis, we performed a multilevel study using targeted re-sequencing and whole-transcriptome profiling. We develope  ...[more]
