Analysis of slc19a2, on 1q23.3 encoding a thiamine transporter as a candidate gene for type 2 diabetes mellitus in pima indians

Mol Genet Metab. 2001 Apr;72(4):360-3. doi: 10.1006/mgme.2001.3154.


Mutations in the SLC19A2 gene cause thiamine-responsive megaloblastic anemia (TRMA) frequently combined with diabetes mellitus and deafness. Type 2 diabetes mellitus is heritable and a region on 1q21-q23 encompassing SLC19A2 was linked with the disease in Pima Indians and Caucasians. We therefore investigated this candidate gene in selected diabetic and nondiabetic Pimas and found no variants. We conclude that mutations in SLC19A2 do not contribute to type 2 diabetes in this population.
