[System of collection and dynamic processing of information for predicting population genetics]. / Systema zboru ta dynamichnoï obrobky informatsiï dlia prognozuvannia genetychnykh protsesiv u populiatsiï liudyny.

Creation has come to be necessary in Ukraine of a system for collection, dynamic supply and processing of information about genetical processes. Such a system as that described above is submitted by the authors. The basis of the system is a module in which, by using special units and connections between them, a collection, storing, and processing of information about genetic pathological processes in the time-related course is to be carried on together with prognostication thereof in the population of the country as a whole or in each region taken separately.

[An approach to genetic monitoring via a genetic registry]. / Pidkhid do henetychnoho monitorynhu cherez henetychnyi reiestr.

The analysis of the selective excerpt of the children with the inherited disorders has been made on the basis of the Kiev Medical Genetic Center, where the regional anonymous syndromological computer register has been organized. Register's file during 1993-96 has the information about 883 families that has a genetically ill proband. Genetic syndrome has been diagnosed in 78.02% (105 nosological points). The information taken from the register has allowed for the first time to distinguish the inherited pathology from the acquired one, so the new mutation from 30.23% out of all registered inherited disease. The necessity of the creation of the National Genetic Register in the Ukraine and the new conception of the two-stage genetical monitoring of the population has been proved.

[Genetic or ecogenetic consequences of the Chernobyl accident? (facts and hypotheses)]. / Henetychni chy ekohenetychni naslidky Chornobyl's'koï avariï? (fakty ta hipotezy).

The results of investigations indicated the necessity of genetic monitoring in population using the data of family examination in medical genetic centres. Indices of the frequency of developmental abnormalities in newborns are not suitable for monitoring because they do not permit to differentiate between new mutations and inherited ones. The dissemination of these abnormalities among newborns in Kiev mostly coincides with the same index in other European regions and is lower than in Canada and West Australia. According to the data of Kiev regional medical genetics centre, about 80% of developmental abnormalities occur as a result of inherited mutations but not new ones. Under the conditions of environmental pollution, ecogenetic consequences assume a new importance.

[The clinico-genetic aspects of mental retardation related to the fragile-X chromosome]. / Kliniko-henetychni aspekty rozumovoï vidstalosti, zv'iazanoï z lamkoiu X-khromosomoiu.

This review deals with main problems of syndrome of X-fragile chromosome. The history of discovery and subsequent study of diseases as well as methods of examination, main clinical symptoms, methods of treatment and prophylaxis have been described. Some hypotheses, explaining complicated mechanism of fra-X syndrome inheritance are discussed. The recent achievements of molecular and genetic investigations of mental backwardness, associated with X-fragile chromosome are included in review.
