In the new study, the authors studied germline cells from 130 children using a genome-wide method
The fact is that mutations and other genetic changes in germline cells are inherited, unlikesomatic cells.
Thanks to the development of the latest methods of genomicsequencing only recently has it become possible to study at the population level the complete triple genome of the father, mother and child, which is necessary for de novo mutation counting.
Scientists today are evaluating DNMs in the population atthe level of 50-100 new mutations per individual in a generation. The results of a new study show that children whose parents were exposed to radiation at the Chernobyl nuclear power plant, this figure does not exceed the population average, and they do not have excessive mutations in the cells of the germ line.
Our research does not confirm the transgenerational effect of ionizing radiation on the DNA of the human germ line.
