Next-generation Sequencing03:00

Next-generation Sequencing

91.5K
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....

Genomics

36.5K
Genomics is the science of genomes: it is the study of all the genetic material of an organism. In humans, the genome consists of information carried in 23 pairs of chromosomes in the nucleus, as well as mitochondrial DNA. In genomics, both coding and non-coding DNA is sequenced and analyzed. Genomics allows a better understanding of all living things, their evolution, and their diversity. It has a myriad of uses: for example, to build phylogenetic trees, to improve productivity and...

Sanger Sequencing01:57

Sanger Sequencing

754.8K
DNA sequencing is a fundamental technique that is routinely used in the biological sciences. This method can be applied to a range of questions at different scales - from the sequencing of a cloned DNA fragment or the study of a mutation in a gene up to whole-genome sequencing. However, despite the widespread use of sequencing today, it was not until 1977 that Fredrick Sanger and his collaborators developed the chain-termination method to decode DNA sequences. It relies on the separation of a...

CRISPR01:59

CRISPR

52.4K
Genome editing technologies allow scientists to modify an organism’s DNA via the addition, removal, or rearrangement of genetic material at specific genomic locations. These types of techniques could potentially be used to cure genetic disorders such as hemophilia and sickle cell anemia. One popular and widely used DNA-editing research tool that could lead to safe and effective cures for genetic disorders is the CRISPR-Cas9 system. CRISPR-Cas9 stands for Clustered Regularly Interspaced...

Genetic Screens02:46

Genetic Screens

5.0K
Genetic screens are tools used to identify genes and mutations responsible for phenotypes of interest. Genetic screens help identify individuals or a group of people at risk of developing  genetic diseases and help them with early intervention, targeted therapy, and reproductive options.
Forward genetic screens
Forward or “classical” genetic screens involve creating random mutations in an organism’s DNA using radiation, mutagens, or insertion of additional bases, which...

Issues And Trends In Healthcare Delivery System

5.7K
The issues and trends in healthcare delivery are constantly changing. The COVID-19 pandemic is one recent issue that wreaked havoc on healthcare systems, causing a shortage of healthcare workers, high demand for medicines and supplies, and increased medical expenditure due to a lack of insurance. Other issues include rising healthcare costs and care fragmentation.
Cost Containment
Payment for healthcare services has historically promoted adoption of costly and often unnecessary or inefficient...

Area of Science:

  • Genomics
  • Pediatric Medicine
  • Medical Ethics

Background:

  • Genome sequencing (GS) aids in diagnosing rare genetic conditions in critically ill newborns.
  • Current studies focus on highly selected patient groups, yielding high diagnostic rates.
  • The utility of GS in broader, general populations remains largely unknown.

Purpose of the Study:

  • To evaluate the effectiveness and challenges of genome sequencing in diagnosing rare genetic conditions in newborns.
  • To explore the impact of GS on clinical management and parental understanding.
  • To identify areas for future research in diagnostic genomic testing.

Main Methods:

  • Review of existing studies on genome sequencing in pediatric populations.
  • Analysis of potential challenges including diagnostic yield, ambiguous results, and cost-effectiveness.
  • Consideration of ethical implications and the need for informed consent.

Main Results:

  • GS successfully diagnoses rare genetic conditions in selected infants.
  • Potential for increased ambiguous results and false positives as GS use expands.
  • Genetic counseling becomes more complex, requiring realistic parental expectations.

Conclusions:

  • Diagnostic genome sequencing for newborns is an emerging field requiring further research.
  • Careful evaluation of GS in general populations is necessary to understand its true impact on outcomes.
  • Personalizing genomic testing requires addressing technological and ethical considerations.
