ABSTRACT
Ror fetal sex determination by the PCR method, oilgoprimers to Y- chromosome gene, DYZI, SRY, and AMGL were synthesized genomic DNA was extracted from male and female placenta for the control use. DYZI represented 154 bp single band to 0.001 pg/ml male genomic DNA but did not represent 154 bp band in female genomic DNA, SRY represented 341 bp bandto 1 pg/ml male genomic DNA in 2% agarose gel eleftrophoresis stained with ethidium bromide. DYZI was 1,000 fold sensitive than Sry and AMGL. DYZI and SRY could not identify the PDR failure from female but AMGL identified to 1,000-fold. During the dyal ampiification of female genomic DNA mixed with male genomic DNA, 0.00125 pg/nl, 1400 part, male genomic DNA contamination represented male band but SRY amplification did not represent male band. It was suggested that SRY gene was deleted in two 46,XY felmle cases. For fetal sex determination, PCR with DYZL, SRY, and AMGL was performed in 10 cases. For fetal sex determination, PCR with DYZL, SRY, and AMGL with karyotyping in 10 cases of chorionic villi sex dietermination, PCR with DYZI, SRY, and AMGL was performed in 10 cases. For feral sex determination, PCR with DYZI, SRY, and AMGL with karyothping result, fetal sex determination, PCR with DYZI, SRY, and AMGL was performed in 10 Cases of choricinic villi and 15 cases of amnionic cells. By the comparison with karyotyping result, fetal sex determination was achieved successfully in all 23 samlies using PCR of SRY and AMGL but false result was detected in 3 cases(13%) using DYZI. Acording to our results, it was concluded that DYZL was 1,000-fold sensitive than SRY and AMGL but could not be used because of its false results, and AMGL and SRY must be used concomitantly for precise sex determination.
