Abstract:
Rogers syndrome is an extremely rare autosomal recessive syndrome of which only 100 cases are known worldwide. It is characterized by thiamine-responsive megaloblastic anaemia, diabetes mellitus and sensorineural deafness. It results from the deficiency of a thiamine transporter protein. We herein report a 16-year-old Indian male referred to our centre with complaints of refractory anaemia, deafness, diabetes pulmonary arterial hypertension and tricuspid regurgitation. Based on the clinical features and haematologic picture and dramatic response of anaemia to thiamine therapy the possibility of a TRMA was considered. Sequencing analysis for TRMA revealed a homozygous c.242dup (p.Tyr81Ter) mutation of the SLC19A2 gene.

The Retinoblastoma Gene
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...
Glucose Transporters
Facilitated diffusion-glucose transporters (GLUTs) are encoded by the solute-linked carrier (SLC) family 2, subfamily A gene family, or SLC2A. The 14 GLUT protein members are distributed into three classes:
Translation
Translation is the process of synthesizing proteins from the genetic information carried by messenger RNA (mRNA). Following transcription, it constitutes the final step in the expression of genes. This process is carried out by ribosomes, complexes of protein and specialized RNA molecules. Ribosomes, transfer RNA (tRNA), and other proteins produce a chain of amino acids—the polypeptide—as the end product of translation.
