Abstract

Several variable number of tandem repeat (VNTR) DNA polymorphisms detecting different loci (YNH24/MspI or TaqI, CMMIOI/Mspl or MLJ14/MspI, EFD64.2/RsaI or HinfI, YNZ22/TaqI, AW101/EcoRI, EKMDA2.1/Pvull and 3ʹ-HVR/PvuII) were used in the analysis of 27 cases of disputed paternity in the Italian population. Fourteen exclusions and 17 attributions were performed. The results were compared with those obtained with immunohematologic analyses. Four exclusions and 2 attributions were made possible only by the combined use of several DNA polymorphisms, as the analyses of red-blood-cell antigens and isoenzymes, serum proteins and HLA group determinants were inconclusive. With the DNA test, 10 exclusions and 15 attributions were confirmed, with increased overall probability. In conclusion, VNTR polymorphisms were more informative, accurate and sensitive than the immunohematologic tests. Therefore, DNA analysis is the method of choice for testing genetic relationships.
