Three stories from the world of medical genetics

A huge field of application of personal genomics is the study of the genetics of various medical and physiological features: from a tendency to baldness and obesity to a predisposition to serious diseases.

Nephew of his own dad

American geneticists reported a case of so-called "genetic chimerism": the child inherited the genes not of the father, but of his twin brother, who died in the womb.

Men pass on the stress response by inheritance

Under stress in male mice, special microRNAs enter the spermatozoa, which, during the formation of a zygote, block the work of individual maternal matrix RNAs and thus affect the formation of the fetal nervous system.

Typical Yakut hereditary disease: thoughts about

It is not the number of hereditary diseases that is growing, but the amount of our knowledge about them. It's just that many similar cases went unnoticed before, because there were no diagnostic methods. hereditary diseases,

Solving the Peto Paradox

Elephants, despite their size and long lifespan, get cancer less often than smaller species. This paradox was named after Richard Peto, a British epidemiologist from Oxford, who noticed it back in the 1970s.

How Epigenetic Heredity works

The mice conceived with the help of spermatozoa completely cleared of epigenetic marks almost universally suffered from the most serious developmental defects, anomalies in the structure of the skeleton, and many of them did not even live to be born.

Epigenetics and homosexuality

Methylation features in nine small DNA regions scattered throughout the genome can be used to predict sexual orientation with a probability of up to 70%.

Perfect genetic knowledge

Genomics is just the beginning: the total mass of all DNA on Earth is 50 billion tons. What will happen when we get our hands on the whole biocode?

"The binge gene"

Scientists have found a possible genetic and biological explanation for why some people often go into binge drinking – their fault may be special mutations in the ALDH1a1 gene responsible for the withdrawal of alcohol from the body.

The end of the beginning of genome decoding

The most important result of 1000 Genomes Project is the compilation of a catalog of human gene variations and the analysis of methods and tools that can be used for further sequencing of the human genome. This catalog is completely free and is publicly available.

Mutating humanity

In the 15 years that have passed since the first rough reading of the human genome, our knowledge of mutations that occur in our genes has increased many times, and the methods of studying them have become much more effective and diverse.

An emotion enhancer gene

Owners of one of the SERT gene varieties are more prone to depression if life cracks, but they are happier if everything goes well.

Educational program on DNA reading technologies

Sequencing (from sequence – sequence) is called determining the order of elementary units of monomers in a polymer. Moreover, this polymer can be not only DNA or RNA, but also, for example, a protein or even a polysaccharide.

Cellular Anthropology

The differences in appearance between humans and monkeys are due not to the appearance of new genes, but to changes in the work of old ones.
