Objective: We estimated the value of chromosomal instability as a factor that caused the congenital or hereditary diseases.
Materials and methods: We analyzed160295 cases (statistical data of the Ministry of Public Health of Ukraine, F. 49 “Report of Medico-Genetic Center (consultations, cabinet)” in 2000-2015; 2090 cases (monitoring data, performed in Kyiv oblast) in 1999-2003 and 2009-2015; 6899 cases (monitoring data of medico-genetic department of the diagnostic center of Zhytomyr oblast) in 1998 -2015.
Results: In Ukraine, the multiple congenital malformations are diagnosed from year to year which really hide undiagnosed syndromes, such as the Nijmegen, Louis Bar syndromes and many others. In general, the cases of chromosomal instability syndromes were single, and the structure of multiple congenital malformations at the whole territory of Ukraine was in the range of 3.5-4.6 % (according to the data of F. 49 Ministry of Public Health of Ukraine)in 2000-2015, in Kyiv oblast – up to 7 % (according to the data of genetic monitoring)in 1999-2003 and 2009-2015, in Zhytomyr oblast – up to 17 % (according to the data of medico-genetic department of the diagnostic center in Zhytomyr oblast) in 1998-2015.
Conclusions : In the course of the research, it was confirmed that the chromosomal instability may have been a possible remote effect of radiation exposure which had been previously established in the field and experimental studies. The Fanconi anemia, ataxia telangiectasia, the Bloom, Nijmegen, Cocaine syndromes and pigmented xeroderma, as well as the Werner's syndrome, fall in the hereditary diseases united in to a group of the syndrome of chromosomal instability (SCI). Taking into account a low level of hereditary diseases, united into the SCI group, the research of the remote effects of chromosomal instability require the further deepening of the analysis with the consolidation of temporal and spatial characteristics.
