Children with progressive neurological conditions such as spinal muscular atrophy, Friedreich's ataxia, familial dysautonomia (Riley-Day syndrome), and Charcot-Marie-Tooth disease have a significant risk of acquiring a serious spinal deformity. As with paralytic scoliosis following poliomyelitis, the curves are difficult to control with bracing, and progression does not cease with maturation. An increasing spinal curvature may lead to loss of ambulation or, for the wheelchair-bound patient, loss of sitting balance. The curvature may further compromise pulmonary function that may already be compromised by the neurological deficit. Twenty patients are reported with an average follow-up of six years (range, one to fourteen years). For the properly selected patient, surgical stabilization of the spine arrested the progress of the curve and improved function. Complications were few; however, pseudarthrosis was more common than in patients with non-neurological problems.

Back pain is a frequent complaint seen in neurological practice. In evaluating back pain, neurologists are asked to evaluate patients for radiculopathy, determine whether they may benefit from surgery, and help guide management. Although disc herniation is the most common etiology of compressive radiculopathy, there are many other causes, including genetic disorders. This article is a discussion of genetic disorders that cause or contribute to radiculopathies. These genetic disorders include neurofibromatosis, Paget's disease of bone, and ankylosing spondylitis. Numerous genetic disorders can also lead to deformities of the spine, including spinal muscular atrophy, Friedreich's ataxia, Charcot-Marie-Tooth disease, familial dysautonomia, idiopathic torsional dystonia, Marfan's syndrome, and Ehlers-Danlos syndrome. However, the extent of radiculopathy caused by spine deformities is essentially absent from the literature. Finally, recent investigation into the heritability of disc degeneration and lumbar disc herniation suggests a significant genetic component in the etiology of lumbar disc disease.

Hereditary optic neuropathies comprise a group of clinically and genetically heterogeneous disorders. Two subgroups can be formed: isolated hereditary optic atrophies and optic neuropathy as part of complex disorders. In group 1 of hereditary optic neuropathies, optic nerve dysfunction is typically the only manifestation of the disease. This group comprises autosomal dominant, autosomal recessive and X-linked recessive optic atrophy and the maternally inherited Leber's hereditary optic neuropathy. Among the autosomal-dominant forms of optic atrophy, Kjer's disease is most frequently observed. In the second group of complex disorders, various neurologic and other systemic abnormalities are regularly observed. Most frequent in this group are mtDNA mutations, inherited peripheral neuropathies, Charcot-Marie-Tooth disorders (CMT2A2, CMTX5), hereditary sensory neuropathy type 3 (HSAN3), Friedreich's ataxia, leukodystrophies, sphingolipidoses, ceroid-lipofuscinoses and neurodegeneration with brain iron accumulation. We review current knowledge about the underlying genetic predispositions, the most urgent open questions and how this may affect our management of this heterogeneous group of disorders in the future.
