| A rare inherited mitochondrial disease characterized by the clinical features of Leber hereditary optic neuropathy in combination with other systemic or neurological abnormalities. These abnormalities include postural tremor, motor disorder, multiple sclerosis-like syndrome, spinal cord disease, skeletal changes, Parkinsonism with dystonia, anarthria, motor and sensory peripheral neuropathy, spasticity, mild encephalopathy, and cardiac arrhythmias. |

| Early-onset X-linked optic atrophy is a rare form of hereditary optic atrophy, seen in only 4 families to date, with an onset in early childhood, characterised by progressive loss of visual acuity, significant optic nerve pallor and occasionally additional neurological manifestations, with females being unaffected. |

| A rare, genetic, X-linked syndromic intellectual disability disorder characterized by severe intellectual disability, microcephaly, post-natal growth retardation, severe visual impairment or blindness (due to optic atrophy), severe hearing defect, spasticity, epileptic seizures, restricted large-joint movements and early death (in infancy or early childhood). Facial dysmorphic features (large dysplastic ears and short broad nose) are additionally observed. There have been no further descriptions in the literature since 1993. |

| A rare, complex type of hereditary spastic paraplegia characterized by early-onset progressive spastic paraplegia presenting in infancy, associated with optic atrophy, fixation nystagmus, polyneuropathy occurring in late childhood/early adolescence leading to severe motor disability and progressive joint contractures and scoliosis. |

| A disorder that is characterized by the association of a non-progressive congenital ataxia, severe intellectual deficit, optic atrophy and structural anomalies of the skin vessels. It has been described in five children from a large consanguineous Lebanese family. Short stature and microcephaly were also reported. Transmission is autosomal recessive. |

| Wolfram-like syndrome is a rare endocrine disease characterized by the triad of adult-onset diabetes mellitus, progressive hearing loss (usually presenting in the first decade of life and principally of low to moderate frequencies), and/or juvenile-onset optic atrophy. Psychiatric (i.e. anxiety, depression, hallucinations) and sleep disorders, the only neurologic abnormalities observed in this disease, have been reported in rare cases. Unlike Wolfram syndrome, patients with Wolfram-like syndrome do not report endocrine or cardiac findings. |

| A rare combined immunodeficiency disorder characterized by primary immunodeficiency manifesting with repeated bacterial, viral and fungal infections, in association with neurological manifestations (hypotonia, cerebellar ataxia, myoclonic seizures), developmental delay, optic atrophy, facial dysmorphism (high forehead, hypoplastic supraorbital ridges, palpebral edema, hypertelorism, flat nasal bridge, broad nasal root and tip, anteverted nares, thin lower lip overlapped by upper lip, square chin) and skeletal anomalies (short metacarpals/metatarsals with cone-shaped epiphyses, osteopenia). |

| A group of rare genetic neurodegenerative diseases with characteristics of infancy to childhood onset of progressive spastic paraplegia (with delayed motor milestones, gait disturbances, hyperreflexia and extensor plantar responses), optic atrophy (which may be accompanied by nystagmus and visual loss) and progressive peripheral neuropathy (with sensory impairment and distal muscle weakness/atrophy in upper and lower extremities). Additional signs may include foot deformities, spinal defects (scoliosis, kyphosis), joint contractures, exaggerated startle response, speech disorders, hyperhidrosis, extrapyramidal signs and intellectual disability. In very rare cases, a variant phenotype with less prominent or absent optic atrophy and/or neuropathy may be observed. |

| A rare, genetic, developmental defect during embryogenesis malformation syndrome characterized by severe postnatal growth retardation, craniofacial dysmorphism, which includes a progeroid facial appearance, brachycephaly with hypoplasia of the frontal and parietal tubers and a flat occipital area, narrow forehead, prominent glabella, small orbit, slight bilateral exophthalmos, straight nose, hypoplastic cheekbones, long philtrum and thin lips, skeletal abnormalities (i.e. micromelia, brachydactyly, and severe short stature with short limbs), normal intelligence, Pelger-Huët anomaly of leukocytes, loose skin with decreased tissue turgor, and bilateral optic atrophy with loss of color vision and visual acuity. Recurrent liver failure triggered by fever has been occasionally reported. Radiographs may evidence delayed bone age, late ossification and/or osteoporosis. |
