Insights

The BabySeq Project explored genomic sequencing in newborns. Returning adult-onset genetic results, even for family benefit, raises ethical concerns for pediatric research.

Area of Science:

  • Genomic sequencing in pediatrics
  • Ethical, legal, and social implications (ELSI) of genomic medicine
  • Newborn screening and genetic testing

Background:

  • The BabySeq Project investigated the impact of genomic sequencing in newborn care.
  • Initial protocols returned only childhood-onset conditions, but a BRCA2 finding caused ethical distress.
  • This led to a protocol revision allowing return of adult-onset results, citing 'family benefit'.

Purpose of the Study:

  • To describe the BabySeq Project and the controversy surrounding predictive genetic testing in children for adult-onset conditions.
  • To examine the ethical issues of the revised BabySeq protocol and the 'family benefit' justification.
  • To argue against using family benefit to expand genomic sequencing in children beyond childhood-onset conditions.

Main Methods:

  • Analysis of the BabySeq Project's study design and ethical considerations.
  • Examination of the moral distress experienced by researchers regarding genetic result disclosure.
  • Ethical critique of the revised protocol and the concept of 'family benefit'.

Main Results:

  • The study identified ethical problems with the revised BabySeq protocol.
  • The concept of 'family benefit' was found to be an insufficient moral justification for returning adult-onset results.
  • The research team experienced moral distress over the nondisclosure of a BRCA2 mutation.

Conclusions:

  • Family benefit should not justify returning adult-onset genetic results in pediatric genomic sequencing.
  • Researchers should aim to avoid identifying adult-onset-only variants in pediatric studies.
  • Return of adult-onset results should be limited to cases relevant to the child's current or imminent health.

CRISPR

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...

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.

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...

Sanger Sequencing

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...

Maxam-Gilbert Sequencing

In the same year as the discovery of the Sanger sequencing method, another group of scientists, Allan Maxam and Walter Gilbert, demonstrated their chemical-cleavage method for DNA sequencing. The Maxam-Gilbert method relies on using different chemicals that can cleave the DNA sequence at specific sites, the separation of resulting DNA fragments of variable size using electrophoresis, and deciphering the DNA sequence from the resulting gel bands.

Animal Mitochondrial Genetics

Among all the organelles in an animal cell, only mitochondria have their own independent genomes. Animal mitochondrial DNA is a double-stranded, closed-circular molecule with around 20,000 base pairs. Mitochondrial DNA is unique in that one of its two strands, the heavy, or H, -strand is guanine rich, whereas the complementary strand is cytosine rich and called the light, or L, -strand. Compared to nuclear DNA, mitochondrial DNA has a very low percentage of non-coding regions and is marked by...
