  • First Gene Mutation in Humans found by Genetic Engineers

The first gene mutation in humans was found by genetic engineers.

The earliest signs of genetic mutations in human beings were discovered by scientists recently. Genomes from adult cells showed how embryonic development took place with a difference.

Apparently, the two cell development of the human embryo was studied in depth by the researchers. What exactly occurred on a genetic level in embryonic humans remained pretty much a mystery. Yet now we know better due to further in-depth research.

The blood samples from 279 human beings were examined. The genome gave proof of 163 mutations. Once these were pinpointed, the researchers used mutations from the first, second and third divisions of the zygote to gauge which part of the adult cells formed from the embryonic cells.

It was ultimately discovered that the first two cells have a different contribution to make to the whole body. One of the cells gives rise to 70% of the adult tissues.

The other one has a minor role and gives rise to 30% of the adult tissues. The role these two cells played in the genesis of cancer was studied in a thorough manner.

The whole research effort was rather like finding something small hidden in a rubble of odds and ends. The process of embryogenesis which was involved in the cancer genes was a complex science.

A couple of mutations had so many variations that only expressed themselves later on in adult life. It all starts at the beginning of the development of human life. And the earlier the mutations take place, the more far reaching their effects.

The mutations lead to a doubling of the chances of cancer in every daughter cell. As for the mutations, they are random in their nature. This research is quite exciting since it proves that the oldest of mutations have the greatest of impacts on the future organism.

The research was published in the journal Nature.
