Inherited Disorders of Cobalamin Metabolism in Childhood: Biochemical and Clinical Perspectives
The review outlines inherited cobalamin (vitamin B12) metabolism disorders that cause severe neurological injury in children. It details the biochemical pathways, the spectrum of genetic complementation groups (cblC, cblD, cblE, etc.), and the characteristic elevations of methylmalonic acid and homocysteine. Clinical presentation ranges from neonatal encephalopathy and seizures to later‑onset neuropathy, with MRI often revealing white‑matter and spinal cord lesions. Prompt diagnosis using targeted biomarkers and molecular testing, followed by aggressive parenteral B12 therapy, can avert irreversible damage.
