摘要
Reliability of preimplantation genetic diagnosis (PGD) depends on controlling one of the most important limitations of single cell PCR, undetected allele drop out (ADO), which may lead to misdiagnosis. To avoid this we introduced mutation analysis simultaneously with linked polymorphic markers, pre-selecting only those embryos whose unaffected status could be confirmed by at least one linked polymorphic marker. We applied this strategy for testing 1047 oocytes, from which 237 unaffected ones were pre-selected for transfer back to patients, resulting in 34 unaffected pregnancies and birth of 23 healthy children. Embryos originating from mutant oocytes and those with insufficient marker information were followed up by multiplex PCR to confirm single cell PCR diagnosis. Of 75 (8.5%) detected ADO, only seven (under 1%) were missed in the actual PGD, demonstrating high reliability of PGD (98%) based on multiplex single cell PCR.
