[Genetic markers of atypical phasic psychoses].

The 93 patients of the present study resemble each other in their psychosis by phasic course and complete recovery. Frequently the attacks showed an anxious and paranoid syndrome in monopolar repetition or in bipolar change with ecstatic symptoms. Rarely an incoherent state of agitation or stupor could be observed. Considering the distribution of simple inherited serum groups, there is a significant increase of Gc 1-1 and Hp 2-2 in the patient collective. Evidently these serum groups are risk components in a multifactorial hereditary system possessing with Gc 1-1 a marker of the schizophrenic disposition and with Hp 2-2 a determinating trait for affective psychoses. A selective interaction is discussed for both serum groups regarding the vitamin D transport of the Gc fraction with their relation to enuronal function and the possible role of Hp 2-2 in a transport or regulatory system.
