The latest research in genetics: advances and discoveries
The latest advances in genetics since 2000: research and conclusions
Although little by little patterns were being deciphered, such as the genetic fingerprint (1984) , only the discovery of the complete human genome has favored the multiplication of therapeutic and diagnostic uses.
Genetics also goes beyond the merely clinical. It also serves to establish our evolutionary history and to improve certain production processes. The development of AI, for example, has helped make new discoveries that were previously impossible due to lack of technology.
The qualitative leap that genetics has made so far in the 21st century has been enormous. Therefore, it's worth exploring its main milestones. Are you up for it?
1. First draft of the human genome (2000)
He The first draft of the human genome , a child of the project of the same name, was released in 2000. This project It had been started in 1990, so after 10 years, the first result had already been achieved.
The transcendence of the first draft of the human genome was such that, On April 6, 2000 , the discovery was presented publicly. Although many questions remained, it served as a first guideline. This draft, for example, was already of significant use in understanding the origins of large human groups.
It should be noted that genetic research was already being used to determine paternity or solve crimes. However, the margins of error were still relatively high, even though certain markers were already known.
2. The complete map of the human genome deciphered (2003)
He The complete decoding of the human genome map , providing a sequence, was achieved in 2003. In this case, a list with a very significant level of detail was presented on April 14. It therefore represented a quantitative leap forward compared to the 2000 draft.
In this way, it was possible to conclude that the human genome is the complete DNA sequence, divided into 24 fragments that make up 23 pairs of chromosomes. In total, we can say that each individual has between 25,000 and 30,000 genes, distinct, unique, and unrepeatable. And knowing the complete map of the genome, by comparing it, has also served to decipher the main mutations that are generated.
This milestone has been fundamental, for example, in establishing the genetic origin of a multitude of diseases. Cystic fibrosis, for example, is one of them, but so are thalassemia, Huntington's disease, Down syndrome, sickle cell anemia, and certain muscular dystrophies.
3. Human Epigenome Project (2008)
The epigenetics It has gained importance in recent years because our interaction with the environment also influences DNA. It's no surprise, then, that work has been carried out at another level to decipher the epigenetic implications.
To date, we can say that, thanks to this model, elements have been discovered that influence genetics, but not the DNA sequence. This has been especially important, for example, in preventing certain diseases or proposing treatments. The Roadmap Epigenomics Project , underway since 2008, has found numerous changes and mutations in cells.
Epigenetics also serves to raise awareness through outreach. Therefore, the advances of this project and others have been very useful.
4. Missing DNA decoded (2022)
For years, a portion of DNA remained undeciphered or its function was unknown. At that time, this part of the genetic code was mistakenly referred to as "junk DNA."
Well, the March 31, 2022 That research work to understand what was happening was completed. The human genome code . Approximately 8% of genomic regions remained unresolved, their meaning or functionality unknown. And it's worth remembering that only 1% of DNA codes for proteins.
Right now, fragments of the human genome can be sequenced with 99% accuracy. This sequence can also be performed from start to finish. It's no secret that this greatly improves diagnostic techniques and improves the understanding of certain processes.
5. Implementation of CRISPR therapies (2023)
The CRISPR technique It's been known since 2015, but 2023 marked a significant change. The reason? It's now being implemented for therapeutic purposes in some cases.
The best thing of all is that the CRISPR DNA editing technique It has new applications in the medium term. It can be used to treat HIV, infectious diseases, cancer, and perform transplants, among other things. It also has applications to improve industrial productivity. It's no surprise, then, that there is increasing investment in therapies that, until just a few years ago, were a pipe dream.
Although gene editing techniques are highly complex, they are expected to become more widespread in the coming years. For this reason, it's worth considering them because they won't be uncommon to see them in hospitals.
6. Improvements in diagnostic tests for animals (2024)
Improvements in diagnostic tests for animals are another new development in genetic research. It is true that genome of a human and a dog It has high coincidences (10%), but it has managed to enter the analysis of certain ailments.
For example, in 2024, one of the causes of premature blindness in dogs was identified. It's genetic, so genetic selection could minimize this effect on offspring.
Needless to say, many of these advances can also be applied to humans. This is further proof of how advances in genetics are serving an ever-growing population.
In summary…
Advances in genetics in recent decades in sequencing, genes, and markers allow for the detection of possible mutations, but also for genetic compatibility analysis. Genotics You'll find numerous tests, classified by type and cost. Get to know us better!
