In our previous studies, the rapid diagnosis of aneuploidy has been achieved using the segmental duplication molecular markers-based SD-QF-PCR technique. However, it is also insufficient due to the drawbacks including less detection loci and incompetence in single-tube detection.In this paper, we developed 13 new segmental duplications as molecular markers, as well as designed 13 pairs of primers...
During thalassemia screening, a previously unidentified α2 gene variation in α-globin gene cluster was isolated. This variation was distinct from other variations known to confer thalassemia as assessed by conventional thalassemia genotype analysis. Because the sample in the thalassemia screening was positive (MCV=83.6fL, MCH=26.1pg/cell, Hb=11.3g/dL), further analysis was required.MLPA (multiplex...
Development of a qPCR test for the detection of trisomy 21 using segmental duplications.Segmental duplications in the TTC3 gene on chromosome 21 and the KDM2A gene on chromosome 11 were selected as molecular markers for the diagnostic qPCR assay. A set of consensus primers selected from the conserved regions of these segmental duplications were used to amplify internal diverse sequences that were...
Thalassemia is one of the most common monogenic hereditary diseases in tropical and subtropical regions. An effective way to avoid the birth of severe thalassemia patients is to strengthen the thalassemia screening of couples before wives are pregnant. Thalassemia gene carriers can be diagnosed by molecular biology in order to conduct effective guidance for fertility.For -- SEA and -- ...
