Abstract:
Manganese is an essential element that is ubiquitously present in our diet and water supply. It is a cofactor for several critical physiological processes. Elevated blood levels of Manganese secondary to SLC30A10 gene mutation presents distinctly with dystonia, polycythemia, chronic liver disease and a characteristic high T1 signal in basal ganglia on brain MRI. The primary treatment for this condition is chelation along with iron therapy. We report a previously healthy boy with compound heterozygous SLC30A10 gene mutations who had a unique clinical presentation with prominent seizures, polycythemia, and characteristic T1 hyperintensity in basal ganglia. Seizures have not been previously reported to be associated with this specific mutation.

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:
Inborn Errors of Metabolism
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.
