The Leucocyte Antigenic System HL-A as a Possible Genetic Marker of Schizophrenia

Abstract
Many inheritance models of schizophrenia have been proposed, in view of its variable age at onset, variable familial occurrence and the relevant influence of a great number of environmental factors (Gottsman and Shields, 1967; Heston, 1970; Ödegård, 1972). However, the real genetic predisposition to schizophrenia has not yet been experimentally verified, and genetic markers have to be looked for, i.e. we need some character, genetically determined, whose transmission is associated with schizophrenia transmission: the more polymorphous the character, the greater will be the probability of finding such associations.
