Summaries for SLC19A2 Gene

Entrez Gene Summary for SLC19A2 Gene

  • 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]

GeneCards Summary for SLC19A2 Gene

  • Thiamine-responsive megaloblastic anemia syndrome (TRMA) [MIM:249270]: An autosomal recessive disease characterized by megaloblastic anemia, diabetes mellitus, and sensorineural deafness. Onset is typically between infancy and adolescence, but all of the cardinal findings are often not present initially. The anemia, and sometimes the diabetes, improves with high doses of thiamine. Other more variable features include optic atrophy, congenital heart defects, short stature, and stroke. {ECO:0000269 PubMed:10391221, ECO:0000269 PubMed:10874303}. Note=The disease is caused by mutations affecting the gene represented in this entry.
