Defective high-affinity thiamine transporter leads to cell death in thiamine-responsive megaloblastic anemia syndrome fibroblasts.
We have investigated the cellular pathology of the syndrome called thiamine-responsive megaloblastic anemia (TRMA) with diabetes and deafness. Cultured diploid fibroblasts were grown in thiamine-free medium and dialyzed serum. Normal fibroblasts survived indefinitely without supplemental thiamine, whereas patient cells died in 5-14 days (mean 9.5 days), and heterozygous cells survived for more ...

متن کاملThiamine responsive megaloblastic anemia.
This report describes a female child with thiamine responsive megaloblastic anemia syndrome (Rogers syndrome), presenting with anemia and diabetes mellitus responding to thiamine. She also had retinitis pigmentosa. The anemia improved and blood sugar was controlled with daily oral thiamine. Previously unreported olfactory abnormalities, as described in Wolfram syndrome, were also present in our...

A three year old boy presented with sensory neural hearing loss since birth, Diabetes mellitus and anaemia. On investigation he was found to be suffering from thiamine responsive megaloblastic anaemia (TRMA) a very rare condition diagnosed in our settings.
متن کاملNovel mutation in the SLC19A2 gene in Thiamine-responsive megaloblastic anemia (Rogers’ syndrome)
Introduction: The Thiamine Transporter gene SLC19A2 is the only gene known to be associated with TRMA. This syndrome is a trial clinical characterized by megaloblastic anemia, nonautoimmune diabetes mellitus and sensory-neural hearing loss. Methods: Described here are three children from consanguineous Iranian families with thiamine – responsive megaloblastic anemia (TRMA) or Rogers' syndrome....
