Biotin-responsive basal ganglia disease
Written and reviewed by Dr Ibrahim Imam, Consultant Neurologist. Last reviewed .
Biotin-responsive basal ganglia disease. This is caused by mutations in the SLC19A3 gene. Fully referenced neurology checklist.
Genetics and pathology
- This is caused by mutations in the SLC19A3 gene
- The gene encodes the human thiamine transporter 2 (hTHTR2)
- The transmission is autosomal recessive
- It is especially in Saudi Arabia
