Mutations in this gene cause biotin-responsive basal ganglia disease (BBGD); a recessive disorder manifested in childhood that progresses to chronic encephalopathy, dystonia, quadriparesis, and death if untreated. Patients with BBGD have bilateral necrosis in the head of the caudate nucleus and in the putamen. Administration of high doses of biotin in the early progression of the disorder eliminates pathological symptoms while delayed treatment results in residual paraparesis, mild cognitive disability, or dystonia. Administration of thiamine is ineffective in the treatment of this disorder. Experiments have failed to show that this protein can transport biotin. Mutations in this gene also cause a Wernicke's-like encephalopathy.[provided by RefSeq, Jan 2010]. * **UniProt Summary**: Mediates high affinity thiamine uptake, probably via a proton anti-port mechanism. Has no folate transport activity. {ECO:0000269|PubMed:11731220}. |MFS 1| |Folate carrier| |thiamine transmembrane transporter activity| |thiamine transmembrane transport| |thiamine transport| |thiamine-containing compound metabolic process| |pyrimidine-containing compound transmembrane transport| |vitamin transmembrane transport| |azole transport| |vitamin transport| |sulfur compound transport| |drug transmembrane transport| |water-soluble vitamin metabolic process| |pyrimidine-containing compound metabolic process| |vitamin metabolic process| |drug transport| |sulfur compound metabolic process| |drug metabolic process| |response to drug| |transmembrane transport| |small molecule metabolic process| |nitrogen compound transport| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp114|A-196 10μM R03 exp114]]|1.76| No correlation found to any other genes in chemogenomics.
