Neurological symptoms, such as seizures, are rarely reported with Klinefelter syndrome, and it response well to anti-epileptic drugs. A 5-month-old boy visited the Inha university hospital due to jerking movements and hiccups.

The patient’s serum testosterone level was decreased and his anti-Müllerian hormone level was increased. The brain image examination was normal and the electoencephalography and other blood test results showed no specific findings. However, after admission, the patient recurred generalized tonic-clonic-seizures recurred intermittently even after the administration of antiepileptic drugs.
