Diagnosis in Prader-Willi syndrome

Arch Dis Child. 1994 Nov;71(5):441-2. doi: 10.1136/adc.71.5.441.

Abstract

Thirty one patients with the putative diagnosis of Prader-Willi syndrome were reassessed clinically and by DNA analysis. Eleven patients were judged not to have Prader-Willi syndrome and 20 to have the condition. This was confirmed by DNA analysis in all but one case. The diagnosis of Prader-Willi syndrome, especially in early infancy, should be made with caution unless confirmed by molecular genetic studies.
