[The use of the erythrocyte adenylate kinase system in paternity suits].

Authors describe genetically determined polymorphisms, genetical feature and pattern of inheritance of the system of AK. Results and methods used in their studies first in the Hungarian population are reported. On the basis of examination of 1734 persons the incidence of the AK phenotypes was found as follows: AK 1 = 93,59%, AK 2 = 0,05%, and AK 2-1 6,34%. Values of gene frequency: AK1-0,9676, AK2-0,0322. According to the authors findings the maximal (theoretical) chance of the exclusion of paternity on the basis of AK system was 3,02%. In 844 cases of discussed paternity beside the investigation of the systems of A1A2BO, MN, Hp, Rh, Gm/a, x, b), InV(1), Gc, Ss, Kk, Fy(ab), VSP, PGM1, GPT and ADA the system of AK was also studied. In 191 cases (22,62%) the paternity could have been excluded. In 8 cases (0,94%) exclusion of the paternity have been based on the findings of the examination of AK system. In cases of discussed paternity authors recommend the examination of the AK system.
