He reports that his son has been suspended several times over his high school career for instigating fights. Per the patient, he has always had trouble controlling his anger and would feel especially frustrated at school since he has difficulty keeping up. His past medical history is unremarkable and he is up-to-date on all his vaccinations. A physical examination demonstrates a 6-foot tall teenage boy with severe acne vulgaris throughout his face and back. He is later worked up to have a chromosomal abnormality. What is the most likely explanation for this patients presentation?? A: Conduct disorder, B: Down syndrome, C: Fragile X syndrome, D: Klinefelter syndrome, E: XYY syndrome,  <response>: This is a clinical vignette describing a 15-year-old boy with a history of behavioral issues, learning difficulties, and delayed puberty who is found to have a chromosomal abnormality. The key features are aggressionconduct issues, intellectual disability, and delayedincomplete puberty. Down syndrome is unlikely as this condition does not typically present with aggression. Fragile X also does not present with conduct issues. Conduct disorder could explain the aggression, but not the intellectual disability or delayed puberty.The two chromosomal abnormalities that fit this presentation are Klinefelter syndrome 47,XXY and 47,XYY. Klinefelter syndrome classically presents with tall stature, small testes, gynecomastia, and intellectual disability. 47,XYY can present with tall stature, acne, aggression, and learning difficulties.Based on the description of severe acne and the lack of gynecomastia mentioned, 47,XYY syndrome seems the most likely diagnosis.E: XYY syndrome
