HaploSeq: New DNA sequencing technology



 
      ScienceDaily has recently posted an article about a new technique in the world of science, known as HaploSeq. Researcher Bing Ren, Ludwig scientist at the University of California, San Diego School of Medicine led the team to discover the new technique for studying DNA sequencing. Current DNA sequencing tools are becoming faster and cheaper and soon everyone will have their genome sequenced, but there is one problem with it. Ren states that everyone has two copies of each chromosome (accept sex). One copy comes from the mom, and the other comes from the father. The problem is that current technological techniques do not have any way of distinguishing between the two copies of each gene, and are not good at determining whether particular genetic differences come from a person's mother or father. HaploSeq combines molecular biology and computational biology, which enables researchers to quickly determine which genetic variants occur together on the same chromosome, in turn coming from the same parent. This technique will allow clinicians to better asses a person's risk for disease, by enabling them to determine if the gene mutations of that disease (ex: cancer) are on the same chromosome or different chromosomes.

 
 
     Also, HaploSeq offers the opportunity to refine the process of determining whether there is a genetic match between an organ donor and recipient. Genes express a lot of variability and this technique could help researchers and scientists determine whether DNA differences between the donor and recipient are going to be a good match. Furthermore, HaploSeq will also assist researchers in analyzing human migration and determine ancestry from their DNA. This technique will allow each individual and how one relates to other individuals to be studied specifically. As the data accumulates worldwide, researchers will be able to precisely determine their relationships. Ren says this study will become a worldwide human genetic variation, in which will be called the HapMap project.
Overall this new technique of studying DNA sequences seems like a very promising study. It will not only help determine which parent a specific gene comes from, but it will also help with disease risks and allow people to find the ancestrial relations to other individuals. HaploSeq seems like a positive triple threat to me. I think it will do great for the furture.
