详细信息:A differentially methylated site exists in the CpG islands of SNRPN (small nuclear ribonucleoprotein-associated polypeptide N), a candidate gene for Prader-Willi/Angelman Syndrome. Normally, this site is methylated and inactive on the maternal homolog and unmethylated and transcriptionally active on the paternal homolog. In research samples from Prader-Willi individuals, only the methylated allele is present, while samples from Angelman Syndrome (AS) individuals查看全部。CpG WIZ™ Prader-Willi/Angelman Amplification Kit
