India started genomic surveillance early this year to study the mutating nature of COVID-19. The surveillance strategy is aimed at performing genome sequencing as a quick response measure. And bioinformatics tools have come to the rescue here founder taking such genomic test.

Genomic testing

What is Genomic Testing?

Genomic testing is performed to study mutations in a gene. Mutations indicate the presence of disorders and diseases, sometimes as deadly as cancer. Genomic sequencing tests identify differing levels of expression in a group of genes to understand their interactions. Test genomic analysis is thus critical for understanding the activity of genes and making an accurate prognosis.

What are the Different Types of Genomic Testing?

Genomic tests are a kind of medical tests done to rule out the possibility of a person having or developing a medical condition. These types of genomic testing are performed by geneticist or genetic counsellors:

  • Diagnostic testing

Diagnostic testing is used for identifying genetic conditions that an individual may have. These are based on clinical presentations prepared by clinicians to confirm an initial diagnosis. This kind of genomic test is done by checking an allele or a specific gene variant associated with a particular kind of disease. Bioinformatics tools here help with sequencing the genomes for further analysis.

  • Clinical predictive testing

Clinical predictive kind of genomic testing is done to see if or not an individual is susceptible to a certain disorder. Open source and free bioinformatics tools here help with examining the causative gene variant for targeted tests.

  • Pharmacogenomic testing

Open source and free bioinformatics tools for Linux help with pharmacogenomic testing by studying the genomic determinants of different drug responses. This test genomic analysis helps assess whether a particular medicine would be effective.

  • Tumour testing

Tumour testing helps with sequencing of DNAs to study the mutations within them. Bioinformatics tools are deployed here to do tumour testing. This type of genomic testing is quite important when it comes to diagnosing cancers and tumours.

Advances in Genomic Testing to Analyse Health Risks

Genome-wide analysis and testing is critical for testing, monitoring and preventing diseases across populations.

Next generation genome sequencing technology undertakes parallel sequencing of DNA fragments for an efficient genomic analysis. These tests are performed using samples of hair, blood, tissue, amniotic fluid or skin. Some of the most advanced methods today for genomic testing are:

  • Molecular tests for studying short length DNAs or single genes to examine mutations that may lead to genetic diseases.
  • Biochemical test studies the activity level or number of proteins. Any abnormality here indicates the possibility of a genetic disorder.

Genomic testing has evolved newer advanced methods for analyzing the different health risks in new born. This is one area where genomic testing and medicine has advanced well and let us have a look here how:

  • Presymptomatic & predictive testing

Presymptomatic & predictive testing is used in conditions where members of a family suffer from any kind of genetic disorder. This kind of genomic testing studies gene mutations to identify defects that may emerge either after birth or during later stages in life. One good example could be identifying certain types of cancers using presymptomatic & predictive type of genomic testing.

  • Carrier testing

People with increased risk of suffering from a genetic disorder are administered this type of genomic testing. Carrier testing assesses people who have more than one copy of genetic mutation.

  • Prenatal testing

Prenatal kind of test screens a foetus for changes in her or his chromosomes/genes. The process makes it possible to ensure whether the child would have any genetic disorder.

  • Chromosomal tests

Chromosomal tests analyze long length DNAs and whole chromosomes to find out if there are massive genetic changes.

How Bioinformatics Tools Help with Genomic Testing

Bioinformatics software solutions are ideal for genomic testing or next-generation sequencing. Next-generation sequencing technology is used to study mutations in genes for predicting the nature of a disease.  

If we speak about this technology in the Indian context, you would find that India has started genome sequencing of COVID-19 using bioinformatics tools. Covid-19 has protein binding on its membrane and is primarily an RNA virus. It is because of these components that the virus has acquired the character it has and is fast mutating.

How biometric tools work is theydo genome sequencingto study the arrangement of DNA, RNA, and proteins in the virus to understand its changing nature. Bioinformatics tools with their next generation sequencing and genomic testing capabilities have been deployed by scientists in India thus to study such mutations.

Popular bioinformatics software solutions provide computation infrastructure for genomic data analysis.Bioinformatics tools are thus based on multiarray technology for transforming complicated genomic data into valuable insights.

Paid and open-source bioinformatics tools further support the sequencing data analysis for aligning and assembling DNA fragments. You can do variant calling, data visualizations, RNA expression profiling, gene fusion detections and data mining.

These branch diagrams are called phylogenetic trees and they help identify characteristics like genes, organs, and proteins in an organization. 
  • Biological databases in Bioinformatics- Biological databases in bioinformatics can be best understood by analysing its three classifications that exist. The three classifications are- functional, structure and sequence. Protein sequences and nucleic acid is stored in sequence database whereas proteins & RNA exists in structural databases. Physiological role for gene products is provided by functional databases.
