Thiamine transporter 1, also known as thiamine carrier 1 (TC1) or solute carrier family 19 member 2 (SLC19A2) is a protein that in humans is encoded by the SLC19A2 gene.[1][2][3] SLC19A2 is a thiamine transporter.

In melanocytic cells SLC19A2 gene expression may be regulated by MITF.[4]

Clinical significance[edit]

Mutations in this gene cause thiamin-responsive megaloblastic anemia syndrome (TRMA), which is an autosomal recessive disorder characterized by diabetes mellitus, megaloblastic anemia and sensorineural deafness.[5]
