Abstract:
A 4-year-old boy presented with loss of motor milestones following viral fever. On examination, the child had increased tone and exaggerated deep tendon reflexes. Magnetic resonance imaging of the brain showed white matter hyperintensities on T2-weighted images, which revealed partial inversion on fluid-attenuated inversion recovery images. Clinical exome sequencing revealed a novel homozygous mutation c.1270T>G: pCys424Gly in exon 11 of the EIF2B3 gene. This novel mutation is reported in this article along with a literature review.
Insights
A novel mutation in the EIF2B3 gene was identified in a child with progressive neurological decline after a viral illness. This finding contributes to understanding leukoencephalopathy associated with EIF2B gene mutations.
Area of Science:
- Pediatric Neurology
- Neurogenetics
- Molecular Medicine
Background:
- Leukoencephalopathies are a group of white matter disorders affecting brain development and function.
- Mutations in the EIF2B genes are a known cause of vanishing white matter disease, a severe pediatric leukoencephalopathy.
- Early identification and genetic diagnosis are crucial for prognosis and management.

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.
