Background: Biotin-thiamine responsive basal ganglia disease (BTBGD) is an autosomal recessive disorder caused by mutations in the SLC19A3 gene and characterized by recurrent sub-acute episodes of encephalopathy that typically starts in early childhood. This study describes characteristic clinical and magnetic resonance imaging (MRI) findings of six cases of BTBGD diagnosed with newly identified mutations and genetically confirmed, with very early and different presentations compared to cases in the previous literature.
