Abstrakt: A biotechnology for personalized ex vivo gene therapy based on molecular genomic balancing of hematopoietic stem cell (HSC) chromatin with nucleosome monomers of human genomic DNA (hDNA nmr ) has been developed and implemented in the clinic to change (to "correct") mutant chromosome loci genomes of dominant HSC clones that form mono- and oligoclonal hematopoiesis during aging and major (oncological, cardiovascular, neurodegenerative and autoimmune) fatal immune-mediated diseases of civilization. A fundamentally new biotechnological approach has been applied to the delivery of genetic material into eukaryotic stem and progenitor cells by establishing an artificial "recombinogenic situation" in them to induce homologous recombination (equivalent replacement) of mutant DNA regions with healthy hDNA nmr . In experimental preclinical trials, the effectiveness of genomic balancing technology has been proven to reduce the risk of sudden death in old animals and to increase the lifespan of outbred mice by 30% and Wistar rats by 57%. The improvement in their quality of life, compared with the control, is explained by an increase in the telomeric regions of the HSCs and HPCs chromosomes by 1.5-2 times. The potential of the technology to slow down the hereditary neurodegenerative diseases on the model of amyotrophic lateral sclerosis is shown. The effectiveness of this technology in clinical practice is presented on the example of a terminal patient with stage 4 neuroendocrine cancer. This technology used in the treatment of a number of oncological, neurodegenerative, autoimmune and hereditary diseases with clonal hematopoiesis is able to arrest the progression of the disease, prevent its recurrence, prolong the active life of a person, increase the average life expectancy and prevent sudden death.
