WebJun 23, 2014 · One of these diseases is thiamine transporter-2 deficiency (ThTR2, OMIM # 607483), a recessive inherited defect due to mutations in the SLC19A3 gene that cause acute and recurrent episodes of encephalopathy with dystonia, seizures and brain injury that respond extremely well to the early administration of thiamine and biotin [ 6 – 20 ]. WebThe sodium-dependent multivitamin transporter (SMVT) is essential for mediating and regulating biotin entry into mammalian cells. In cells, holocarboxylase synthetase (HCS) mediates covalent binding of biotin to histones; biotinylation of lysine-12 in histone H4 (K12BioH4) causes gene repression. Here we propose a novel role for HCS in sensing …
