Parentage determination on placental tissues through deoxyribonucleic acid fingerprints.
Investigation of genomic polymorphisms detected by a mini-satellite "Myo" probe gives distinct and different Deoxyribonucleic Acid (DNA) fingerprints of chorionic villus and decidual membrane in the same placenta. The chorionic villus, which is regarded as the extra-embryonal tissue, represents the essential embryonal DNA fingerprint pattern, while the decidual membrane reveals the maternal pattern. A comparison between the DNA fingerprints from the chorionic villus and from the blood sample of the suspected father provides the possibility of setting a paternity test in the early gestational stage. Twenty-eight cases of paternity test on aborted placental tissues by DNA fingerprints were analysed.
