Cytogenetic and molecular evaluation of spontaneous abortion samples. Em todos os casos submetidos a mais de um exame os resultados foram concordantes. Forty of these cases were also submitted to fetal sex determination using nested-PCR.

Thirty-two of these cases were selected due to failed cytogenetic culture and the other eight were selected randomly. Thirteen of these samples were selected due to failed cytogenetic culture and the other seven were randomly selected.

The results of samples submitted to more than one test were evaluated for accuracy, using the cytogenetic result as the gold standard. In all cases submitted to more than one test, the results were identical to those obtained through cytogenetic analysis. Samples that failed to grow aneyploidia cytogenetic test and that were submitted to other techniques of molecular biology had a success rate of Molecular biology techniques PCR and FISH complemented the cytogenetic study and proved to be reliable in the detection of numerical chromosomal anomalies and in fetal sex determination.

Todos os 40 casos submetidos ao estudo complementar eram de alto risco, apresentando pelo menos um dos seguintes: Enquanto estes autores realizaram 25 ciclos na primeira etapa e 30 ciclos na segunda euploodia da PCR, no presente estudo aneuploifia utilizados 35 ciclos e 40 ciclos.

Na segunda etapa foram utilizados os primers 3 e 4 15 do pseudogene da amelogenina localizado no qneuploidia Y AMGY. Outro fator relevante seria a idade das pacientes. Chromosomal variation in man: Clinical significance of morphologic and genetic examination of spontaneously aborted embryos.
