Popis: Objective: Rapid diagnosis of Trisomy 21 Syndrome (Down Syndrome) patients usingReal-Time quantitative Polymerase Chain Reaction (Real-Time qPCR) in order to establisha novel method for prenatal diagnosis in the future.Materials and Methods: A total of 5 ml of peripheral blood was obtained from eachpatient and normal controls (NR). Then, genomic DNA from lymphocytes was extractedusing the salting out procedure. Gene dosage levels of DSCAM and (PMP22, DSCAM) inDown Syndrome and NR were analyzed using real-time quantitative PCR. The DSCAM/PMP22 ratio was calculated according to the 2-ΔΔCt formula for all samples.Results: Real-time PCR showed a DSCAM/PMP22 ratio of 1.48 ± 0.18 and 1.01 ± 0.10(p
