Abstract
INTRODUCTION. WHO declared epilepsy one of the most common neurological diseases. According ILAE classification developmental and epileptic encephalopathies (DEE) are generalized genetic epilepsy. DEE represent a clinically and genetically heterogeneous group of age-dependent neurologic disorders characterized by onset of refractory seizures in infancy or early childhood with delayed psychomotor development or developmental regression. Advanced genetic methods have enabled more specific delineation of these clinically defined disorders at the molecular level.
MATERIALS AND METHODS. We tried to search DEE from positions of system genomics. As the basic instrument of search resource OMIM was used (data current as of July 2024). An analysis of the success of predicting cytogenetic loci and functional groups of new genes was performed.
RESULTS. Over 2.5 years, 17 new variants of DEE were described. In 94% of cases, their genes corresponded to the functional groups we had previously published. In 53 % of cases, the genes of new forms were in the same loci as previously known genes. New data allowed us to clarify the boundaries of “hot” cytogenetic loci.
CONCLUSION. The obtained data confirm the high efficiency of the developed predictive model. Testing with new data showed 94 % compliance for physiological mechanisms and 53 % for cytogenetic loci. This model can be applied to other nosological groups.
