摘要
Background: Prader-Willi (PWS) and Angelman’s (AS) syndromes are two distinct clinical entities caused by alterations in an identical but differentially methylated region of DNA on chromosome 15q. Highly complex laboratory tests are required for diagnosis because the disorders are caused by several genetic mechanisms. Methylation-specific PCR (MSPCR) is a relatively simple alternative method to detect the methylation status of the PWS/AS region.
