Abstract


Glutaric aciduria type 1 (GA1) is an organic acidaemia. The objective of this study was to describe the profile of patients diagnosed with GA1 at Inkosi Albert Luthuli Central Hospital, Durban, South Africa from 2007 to 2015. We identified 6 children (4 girls, 2 boys) in a retrospective review. The mean age at diagnosis was 12 months. Clinical findings on presentation were encephalopathic crises (n=4), hypotonia (n=4) and macrocephaly (n=5). Other complications included seizures (n=4), dystonia (n=3) and bulbar dysfunction (n=4). Urine organic acid screens showed elevated glutaric acid levels (n=6). Five patients tested positive for the A293T mutation on the glutarylco-enzyme A (CoA) dehydrogenase gene. Abnormalities on magnetic resonance imaging screening included hyperintense basal ganglia (n=6), widened perisylvian fissures (n=6), and an abnormal signal in the cerebral peduncles (n=5) and central tegmental tract (n=4). All patients were treated with L-carnitine and dietary modification. Two patients had a static clinical course, 1 patient gained milestones, and 3 have shown further neuroregression.
