SLC19A3 (Thiamine transporter 2) variants and mutations

SLC19A3 (also known as Thiamine transporter 2) is a human protein-coding gene encoding a thiamine transporter 2 protein. A high-affinity thiamine transporter that helps supply vitamin B1 to cells, including the brain. Variants can cause biotin-thiamine-responsive basal ganglia disease. This analysis covers 939 SLC19A3 variants and mutations. Of these, 99% have computational variant effect predictions. Disease context includes biotin-responsive basal ganglia disease, hereditary disease, and Leigh syndrome. Example SLC19A3 variants include M1L, D2N, and C3F.
