  • New research shows that transfer ribonucleic acid (tRNA) plays the translator role in human genetics. That is tRNA reads and translates the genetic code into proteins.
  • The scientists working on this study propose that translation errors can cause disease in humans.
  • The differences in the genetic code make some people prone to certain diseases.
  • Most of the research about genetics and disease ignores the role of tRNA. They instead focus on protein-coding mutations.

Quick Summary

The researchers working on this project are from the Western Schulich School of Medicine & Dentistry. To make their findings clear I will compare them with something familiar. Consider any translation app that you use on your smartphone. Now, imagine there is an error in its software programing that regulates the input and output in the app. This error is such that it affects the output even if the input is correct. To put it bluntly, you write white and it translates the word for wheat. Translated into scientific terms the researchers claim that tRNA can have mutations that affect how the code is read. This, in turn, influences the protein formation in our organisms.

Goal

The researchers wanted to uncover the main reason why some people have diseases while others do not. But they didn’t want to look at protein mutations and choose instead to focus on tRNA. Looking at how they influence the development of genetic diseases.

Investigation

The researchers devised a new method for sequencing and reading tRNA, so they can have a better understanding of individual genetic variation. The study looks at transfer ribonucleic acids from 84 individuals that live in London, Ontario. The results show us that every person possesses an average of 66 variations in their tRNA.

Result

The results of the study confirm the scientist’s hunch. That is, not only is the role of tRNA underestimated in the study of genetic diseases. But the study results also show that tRNA can have mutations on it that cause the genetic code to be misread. Also, the scientist claim, the mutations occur in greater volume then we thought before. Practically speaking people with ten wrong transfers have more diseases than those that have one. In addition to this, they also discovered that no two people have the same tRNA.

Limitations

  • The study did not go into details about how tRNA contributes to disease or if the process can be reversed.
