NGS Capabilities

Whole Exome Sequencing (WES) is a wildly used NGS method that involves sequencing every protein coding region (approximately 21,000 genes) to identify any variants that may increase the risk of developing certain conditions or impact health/lifestyle. WES can be used across a broad range of applications including genetic disease, population genetics and cancer studies.

Advantages

  • Attains widespread coverage of coding regions
  • Cost effective alternative to Whole-Genome Sequencing (WGS)
  • Smaller data set provides faster and easy data analysis compared to WGS approaches

Human Whole Genome Sequencing (hWGS) involves sequencing very single base in your DNA (approximately 3.2 billion) to identify any variants that may increase the risk of developing certain conditions or impact health/lifestyle. This sequencing method has many applications including identifying genetic disorders, mutations responsible for cancer progression, as well as monitoring disease outbreaks.

 

Advantages

  • High-resolution view of the genome
  • Detection of all variant types
  • Low cost, fast library preparation

16s rRNA gene sequencing involves the analysis of the prokaryotic 16s ribosomal RNA gene which is found in all bacteria and archaea.

Advantages  

  • Identification and taxonomic classification of bacterial species
  • Fast speed and cost efficient
  • Discovery of novel pathogens

 

Shotgun sequencing reads all the genomic DNA in the sample, rather than just one specific region. This sequencing method provides a vast amount of genetic information as it can identify archaea, bacteria, fungi and viruses.

Advantages

  • Less labour intensive than other sequencing methods.
  • Faster process than clone-clone sequencing
  • Requires less DNA

 

qPCR

qPCR allows for the analysis of particular variants of specific locations. It is a good choice when interrogating  a small region of DNA on a limited number of samples. Real-time PCR can be used for both qualitative and quantitative analysis.

Genotyping Services

 

 

Genotyping Services

The Randox Genomics Services Department currently has target genotyping solutions in multiple areas. Genotyping is the process of analysing DNA to detect SNPs of interest. These SNPs are compared to reference SNPs, available from years of genetic research, to determine differences in genetic makeup.

Genotyping Advantages and Applications

Clinical Diagnostics

  • Can help determine whether specific resistance genes or genetic mutations in bacterial strains- make it insusceptible to one or more antibiotic drug.
  • Can be used to help monitor variants during pandemics, identifying when new variants become more predominant.

Clinical Research

  • Allows researchers to focus on genes, variants, and genomic regions of interest relevant to certain disease or traits of interest.
  • Enables the study of populations not supported by standard products and can be used to create personalised drugs.

Food & Agriculture

  • Identifies potential genes for improving breeding and management programs.
  • Can be used to increase yield and improve quality

Pharmacogenomics

Pharmacogenomics (PGx) is the study of how a person’s DNA effects their drug response. This is a relatively new field in science but it is expected to be the future of medicine as it focuses on personalised medicine and treating every patient individually.

Microarray Technology for PGx

At Randox we use Illumina’s Infinium Global Diversity Array with Enhanced PGx microarray to test for pharmacogenomic markers. This is the most comprehensive genotyping microarray on the market for pharmacogenomic research. The microarray features over 44,000 genome-wide PGx markers which span more than 20000 pharmacogenomic targets and gives 100% coverage of priority level A and B CPIC genes.
