Early myoclonic encephalopathy presents neonatally with fragmented myoclonus and a suppression-burst electroencephalography pattern. We describe a newborn boy with early myoclonic encephalopathy caused by nonketotic hyperglycinemia. He presented with severe hypotonia, progressive apneic episodes, and erratic myoclonus. Screening of deletions in GLDC, using the multiplex ligation-dependent probe amplification method, and a 13C breath test confirmed the diagnosis of nonketotic hyperglycinemia. Treatment with the N-methyl-d-aspartate receptor antagonist ketamine exerted dramatic suppressive effects on his seizures, and ameliorated his clinical status.
