TRANSIENT NEONATAL NONKETOTIC HYPERGLYCINEMIA - A 13-YEAR FOLLOW-UP

We report on a patient with transient nonketotic hyperglycinemia (NKH) . Onset, clinical features, biochemical and electroencephalographic fi ndings were consistent with neonatal nonketotic hyperglycinemia. The n ormalization of clinical, biochemical and electroencephalographic feat ures on day 9 without specific therapy suggested a transient form. At the last follow-up the girl was 13 years old, had a normal mental deve lopment, no EEG abnormalities or neurological deficits.
