Abstract
Biotin–thiamine responsive basal ganglia disease (BTBGD) is an autosomal recessive
neurometabolic disorder, characterized by encephalopathy, extrapyramidal signs following
mild infection, trauma or surgery and is potentially reversible with treatment. We
describe a 15-month-old female child of Indian-Muslim origin with characteristic clinical
and radiological features of BTBGD that showed complete resolution with treatment.
A comparison with previously reported cases reveals a different mutation (exon 2 vs.
exon 5 in middle east cases) in the SLC19A3 gene that could be specific for the Indian subcontinent. We also emphasize the importance
of a trial of vitamins in patients with acute metabolic encephalopathy.
