Background: Deletions and duplications involving large DNA segments result in underexpression or overexpression, depending on the changes in allele dose, and are known to cause many common disorders. Detection of allele dose variations in the human genome is increasingly important in medical genetic diagnosis.
Methods: We used multiplex quantitative PCR coupled with capillary electrophoresis for accurate allele dose determination. In cases of Prader-Willi syndrome (PWS), a total of 24 patients with PWS, as well as 205 control individuals from the general population, were analyzed by use of mu...
