ABSTRACT
To investigate the clinical features, genetic diagnosis, and treatment of a patient with Prader-Willi syndrome(PWS). For a case with clinically suspected PWS, methylation specific PCR(MSPCR)amplification was applied to CpG islands of SNRPN(exon α)gene locus in the 15q11-q13. Furthermore, the diagnosis was comfirmed by the method of bisulfite sequencing PCR(BSPCR). Metabolic status before and after the operation of sleeve gastrectomy were compared. Absence of amplification of paternal allele on chromosome 15q11-q13 was detected in the case by MSPCR, different from the normal control. Results of BSPCR further proved a full methylation of CpG islands in the SNRPN gene locus. Four months after sleeve gastrectomy, systemic metabolic status and ventricular function were improved. MSPCR and BSPCR were both consistent with genetic diagnosis of PWS. Weight loss surgery is expected to be a major therapy of this disease.
