Thiamine-responsive megaloblastic anemia

Thiamine-responsive megaloblastic anemia (TRMA), also known as Rogers syndrome, is a rare autosomal recessive inherited disorder characterized by megaloblastic anemia, diabetes mellitus, and progressive sensorineural deafness, due to mutations in SLC19A2, encoding a high-affinity thiamine transporter protein. In addition to the cardinal components, other findings are also reported in TRMA syndrome including congenital heart disease, arrhythmias, cardiomyopathy, retinal degeneration, optic atrophy, situs inversus, aminoaciduria, and stroke.
