Thiamine-responsive megaloblastic anemia syndrome is a very rare condition characterized by hearing loss, diabetes, and a blood disorder called megaloblastic anemia. Affected individuals begin to show symptoms of this condition between infancy and adolescence. This syndrome is called "thiamine-responsive" because the anemia can be treated with high doses of vitamin B1 (thiamine). This condition is caused by mutations in the SLC19A2 gene and is inherited in an autosomal recessive fashion.[1]
