RNA-seq03:21

RNA-seq

RNA sequencing, or RNA-Seq, is a high-throughput sequencing technology used to study the transcriptome of a cell. Transcriptomics helps to interpret the functional elements of a genome and identify the molecular constituents of an organism. Additionally, it also helps in understanding the development of an organism and the occurrence of diseases. 
Before the discovery of RNA-seq, microarray-based methods and Sanger sequencing were used for transcriptome analysis. However, while microarray-based...
Next-generation Sequencing03:00

Next-generation Sequencing

The first human genome sequencing project cost $2.7 billion and was declared complete in 2003, after 15 years of international cooperation and collaboration between several research teams and funding agencies. Today, with the advent of next-generation sequencing technologies, the cost and time of sequencing a human genome have dropped over 100 fold.
Next-Generation Sequencing Methods
Although all next-generation methods use different technologies, they all share a set of standard features.
Evolutionary Relationships through Genome Comparisons02:54

Evolutionary Relationships through Genome Comparisons

Genome comparison is one of the excellent ways to interpret the evolutionary relationships between organisms. The basic principle of genome comparison is that if two species share a common feature, it is likely encoded by the DNA sequence conserved between both species. The advent of genome sequencing technologies in the late 20th century enabled scientists to understand the concept of conservation of domains between species and helped them to deduce evolutionary relationships across diverse...

Area of Science:

  • Genomics
  • Bioinformatics
  • Quality Control

Background:

  • Exome sequencing is increasingly used for mutation detection in diagnostics.
  • There is a growing need for platform-independent quality control methods for exome data.

Purpose of the Study:

  • To present a novel genotype-weighted metric for assessing exome data quality.
  • To enable comparison of exome variant calls against a reference dataset.
  • To provide a standardized, intuitive quality score.

Main Methods:

  • Developed a genotype-weighted metric for exome data analysis.
  • Compared exome variant calls to a high-quality, ethnically matched reference dataset.
  • Estimated exome-wide genotyping accuracy based on distance to the reference set.
  • Utilized non-metric multidimensional scaling for data visualization.

Main Results:

  • The metric provides an exome-wide genotyping accuracy estimate.
  • Accuracy estimation is independent of data generation specifics or bioinformatics pipelines.
  • Visualizations offer an intuitive and standardizable quality assessment score.

Conclusions:

  • The genotype-weighted metric is a valuable tool for quality control in exome sequencing.
  • This platform-independent method enhances the reliability of diagnostic exome data.
  • The metric facilitates standardized and intuitive quality assessment of genomic data.
