[Haptoglobin subtypes in paternity cases]

A brief review of theoretical and practical problems of the identification of haptoglobins (Hp) is given. Examination of Hp-subtypes was carried out in 335 cases of discussed paternity using polyacrylamide gel electrophoresis. According to the results of the examination of the sera of 285 adults (included into the above mentioned group) the gen frequency appeared to be as follows: when the frequency of the gen Hp1 = 0.346, the value of the frequency of Hp1F = 0.115 and Hp1S = 0.231. Thus the maximal (theoretical) chance of the exclusion of the paternity have been found 26.24%. Two cases are reported. In one of them determination of the Hp-subtypes resulted in exclusion of the discussed paternity.
