mRNA Sequencing
Introduction to mRNA Sequencing
mRNA sequencing (mRNA-Seq) has rapidly become the method of choice for analyzing the transcriptomes of disease states, of biological processes, and across a wide range of study designs. In addition to being a highly sensitive and accurate means of quantifying gene expression, mRNA-Seq can identify both known and novel transcript isoforms, gene fusions, and other features as well as allele-specific expression. mRNA-Seq delivers a complete view of the coding transcriptome that is not restricted by the filter of prior knowledge.

View Recommended WorkflowAdvantages of mRNA Sequencing
mRNA-Seq provides a number of advantages over gene expression arrays in analyzing the transcriptome.
- Offers a broader dynamic range, enabling more sensitive and accurate measurement of fold changes in gene expression
- Captures both known and novel features
- Can be applied across a wide range of species
Transitioning from Arrays to mRNA-Seq
Expression Analysis developed tools to make it easier to compare mRNA-Seq results with previous array data.
Read InterviewAccurate, High-Resolution View of the Transcriptome
Ratio compression is an established technical limitation of gene expression arrays that reduces dynamic range and can mask or alter measured transcriptional changes.1–3 In contrast, mRNA-Seq is not subject to this bias and provides more comprehensive and accurate measurements of gene expression changes.
Additionally, mRNA-Seq can provide strand information, which enables the detection of antisense expression, allows more accurate quantification of overlapping transcripts, and increases the percentage of alignable reads.
Autism and mRNA-Seq
