  1. Variables are reported as the number and proportion of subjects with the characteristic of interest.
  2. p < 0.05: frequency significantly different between groups.
  3. Del15: deletion in chromosome 15 Karyotype; Met+ : diagnosis of Prader–Willi through methylation test (Karyotype unknown); UPD: uniparental disomy Karyotype .
