title: Re-evaluation of hydatidiform mole by DNA fingerprint method: the discrepancy in the diagnoses by pathological finding and the DNA fingerprint method.
abstract: Ten cases of hydatidiform mole (HM) were analysed by the DNA fingerprint method. DNA samples were prepared from HM tissue of HM and maternal and paternal bloods, followed by digestion with HaeIII restriction endonuclease, applied to agarose gel, and then transferred to a nitrocellulose filter. The filter was hybridized using mini-satellite DNA as a probe. A case of partial HM diagnosed by histological findings was revealed to be complete HM using DNA fingerprinting. The case was suggested to be a twin pregnancy with a cHM and an abortion, because the DNA fingerprint of hydropic tissue showed a paternal pattern and that of the non-hydropic tissue did not show such a pattern. DNA fingerprinting was considered to be useful in distinguishing complete HM from partial HM.
