It is generally accepted that patients with cerebral palsy suffer from a static encephalopathy causing a non-progressive disorder of posture and/or movement. We describe 7 patients from 5 families who were initially diagnosed with cerebral palsy. Eventually, excessive excretion of urinary 3-methyl glutaconic acid (3-MGA) was found. The data of our 7 patients are quite similar to the clinical description of Costeff et al (1989): Jewish-Iraqi origin (7/7), consanguinity (2/7), involuntary movements (5/7), ataxia (6/7), pyramidal involvement (6/7) and optic atrophy (6/7). The cognitive functions were intact in 5/7 and 2/7 showed mild to moderate mental retardation. The mean delay in the definitive diagnosis was 9 years. Cerebral palsy-like symptoms accompanied by optic atrophy and extrapyramidal signs should call for extensive metabolic evaluation including the determination of urinary 3-MGA.
