The types of inheritance and clinico-genetical correlatins of epilepsy in 291 probands in conditions of inbreeding were studied. The data obtained confirmed the multifactorial (gene-polygene+medium) inheritance of epileptic and convulsive predispositions and contradicted the hypothesis of primarily recessive inheritance of epilepsy. Together with family forms of the disease, which were communicated mainly according to an uncertained and dominant type (rarely recessive type), there were existed forms of eipilepsy with incomplete genetical hereditary predisposition (which were observed in relatives of 2-3 generations only by epileptic features) and phenotypical forms concentrated in sporadic groups. There were found the dependences onthe rate of occurrence of secondary epilepsy (with or without epileptoidness), epileptoid psychopathy and children convulsions in relatives, on the type of inheritance, the age of manifestations, the form, polymorphism of the attacks, the severity of the developement of epilepsy, the expressiveness of epileptoidness in probands and high severity of the disease with distinct epileptoidness inbreeding families. The hereditary heterogeneity of epilepsy, associated, perhaps, with pleiotropy of epileptic (with or without epileptoidness) genes, was assumed. The found clinico-genetical correlaltions mightbe taken into account in medico-genetical prognosis of families burdened by epilspsy in analogous populational-demographic conditions.
