About this section

Genetics Home Reference:21 Thiamine-responsive megaloblastic anemia syndrome is a rare condition characterized by hearing loss, diabetes, and a blood disorder called megaloblastic anemia. Megaloblastic anemia occurs when a person has a low number of red blood cells (anemia), and the remaining red blood cells are larger than normal (megaloblastic). The symptoms of this blood disorder may include decreased appetite, lack of energy, headaches, pale skin, diarrhea, and tingling or numbness in the hands and feet. Individuals with thiamine-responsive megaloblastic anemia syndrome begin to show symptoms of megaloblastic anemia between infancy and adolescence. This syndrome is called "thiamine-responsive" because the anemia can be treated with high doses of vitamin B1 (thiamine).

MalaCards based summary: Thiamine-Responsive Megaloblastic Anemia Syndrome, also known as rogers syndrome, is related to megaloblastic anemia and diabetes mellitus, and has symptoms including sensorineural deafness/hearing loss, insulin-dependent/type 1 diabetes and macrocytic anemia. An important gene associated with Thiamine-Responsive Megaloblastic Anemia Syndrome is SLC19A2 (solute carrier family 19 (thiamine transporter), member 2), and among its related pathways are Disease and Defective BTD causes biotidinase deficiency. The compounds folic acid and methotrexate have been mentioned in the context of this disorder. Affiliated tissues include heart and skin, and related mouse phenotypes are endocrine/exocrine gland and digestive/alimentary.

NIH Rare Diseases:42 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. last updated: 11/28/2011
