MGI Phenotype

FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes the thiamin transporter protein. 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. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Feb 2016]
PHENOTYPE: Homozygotes for targeted null alleles exhibit a grossly normal phenotype except for reduced testis size and male infertility. On a low-thiamine diet, mutants show premature death and sensorineural deafness, while homozygotes for one targeted allele also display diabetes mellitus and megaloblastosis. [provided by MGI curators]
