Summaries for Thiamine-Responsive Megaloblastic Anemia Syndrome

OMIM : 54 Thiamine-responsive megaloblastic anemia syndrome comprises megaloblastic anemia, diabetes mellitus, and sensorineural... (249270) more...

MalaCards based summary : Thiamine-Responsive Megaloblastic Anemia Syndrome, also known as rogers syndrome, is related to diabetes and deafness, maternally inherited and thiamine metabolism dysfunction syndrome 2, and has symptoms including headache, diarrhea and lethargy. An important gene associated with Thiamine-Responsive Megaloblastic Anemia Syndrome is SLC19A2 (Solute Carrier Family 19 Member 2), and among its related pathways/superpathways are Metabolism of water-soluble vitamins and cofactors and Vitamin digestion and absorption. Affiliated tissues include heart and skin.

Genetics Home Reference : 25 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).

NIH Rare Diseases : 50 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

UniProtKB/Swiss-Prot : 66 Thiamine-responsive megaloblastic anemia syndrome: 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.
