Involvement in diseasei

Thiamine metabolism dysfunction syndrome 2, biotin- or thiamine-responsive type (THMD2)1 Publication

The disease is caused by mutations affecting the gene represented in this entry.

Disease descriptionAn autosomal recessive metabolic disorder characterized by episodic encephalopathy, often triggered by febrile illness, presenting as confusion, seizures, external ophthalmoplegia, dysphagia, and sometimes coma and death. If untreated, encephalopathies can result in permanent dystonia. Brain imaging may show characteristic bilateral lesions of the basal ganglia.
