We report a 12-year-old male with Prader-Willi syndrome (PWS) and 47, XYY syndrome. Genetic work up revealed 47, XYY karyotype. PWS diagnosis was made by polymerase chain reaction methylation and maternal uniparental disomy (mUPD) was determined to be the etiology. Review of distinct behavioral features, possible interplay between the two syndromes and considerations for diagnoses are presented. To our knowledge, this is the first report of behavioral features in PWS with comorbid 47, XYY.
