An increasing number of metabolic disorders with Mendelian and mitochondrial inheritance in children with predominant spinal cord involvement has been recognized. Spinal cord involvement may be isolated; or, more frequently, occur combined with brain involvement. Timely diagnosis and occasional genetic counseling are needed for timely therapy. Therefore, clinicians must be aware of the clinical, laboratory, and radiographic features of these disorders. In this review, we describe pediatric-onset metabolic disorders with Mendelian and mitochondrial inheritance with predominant spinal cord involvement. We overview these conditions to obtain the background and examples of conditions that require rapid identification, focusing on treatable conditions; that are catastrophic if unrecognized.
