[Identification of individual genotype parameters, informative for medical care in piloted space missions: modern and future capabilities].

The factors of space flight provoke some negative shifts in crew health. Improvement of the methods of diagnostics, evaluation of predisposition to diseases and correction of functional deviations is within the scope of the crew medical operations personnel. It is also a new focus of biomedical research referred to as "personalized medicine" the corner stone of which is genetic analysis. Investigations in this area are prediscovery by character; population genetics seems to be the most adequate approach. The authors give examples of candidate genes the genotypes of which could be of significance to medical operations and discuss the genetic safety of space flight. Aside from the applied aspects, the genetic investigations of space crews are of their own concernment in understanding the genetic basis of differences in biological resistance to unhealthy environment.
