Spondylometaphyseal dysplasia-cone-rod dystrophy syndrome is characterized by the association of spondylometaphyseal dysplasia (marked by platyspondyly, shortening of the tubular bones and progressive metaphyseal irregularity and cupping), with postnatal growth retardation and progressive visual impairment due to cone-rod dystrophy. So far, it has been described in eight individuals. Transmission appears to be autosomal recessive. |

Spondyloperipheral dysplasia-short ulna syndrome is a rare, genetic, primary bone dysplasia, with highly variable phenotype, typically characterized by platyspondyly, brachydactyly type E changes (short metacarpals and metatarsals, short distal phalanges in hands and feet), bilateral short ulnae and mild short stature. Other reported features include additional skeletal findings (e.g. midface hypoplasia, degenerative changes in proximal femora, limited elbow extension, bilateral sacralization of L5, clubfeet), as well as myopia, hearing loss, and intellectual disability. |

A rare non-hereditary degenerative ataxia disease characterized by a slowly progressive cerebellar syndrome (with ataxia of stance and gait, upper limb dysmetria and intention tremor, ataxic speech, and oculomotor abnormalities), presenting in adulthood (at around 50 years of age), that is not due to a known cause. Extracerebellar symptoms (e.g., decreased vibration sense and absent or decreased ankle reflexes), polyneuropathy and mild autonomic dysfunction may also be present. Mild cognitive impairment has also rarely been reported. |

Sporadic fetal brain disruption sequence is a rare, non-syndromic, central nervous system malformation disorder characterized by severe microcephaly (average occipitofrontal circumference -5.8 SD), overlapping sutures, keel-like occipital bone prominence, scalp rugae with normal hair pattern and signs of neurological impairment. Brain imaging may show ventriculomegaly, cortical tissue deficit, and hydranencephaly. |

A rare, isolated, non-familial pheochromocytoma/paraganglioma tumor arising from neuroendocrine chromaffin cells of the adrenal medulla (pheochromocytoma) or from extra-adrenal chromaffin tissue (paraganglioma). The majority of these tumors are benign and the presenting symptoms are typically caused by the increased catecholamine production of the tumor, including hypertension (often paroxysmal), tachycardia, anxiety and/or excessive sweating. |

Startle epilepsy is a rare neurologic disease characterized by frequent and spontaneous epileptic seizures (frequently with symmetrical or asymmetrical tonic features) triggered by a normal startle in response to a sudden and unexpected somatosensory (most frequently auditory) stimulus. Falls are common and can be traumatic. In most cases, the disease is associated with spastic hemi-, di-, or tetraplegia and intellectual disability. |

A rare genetic multi-system disorder characterised by a wide range of muscle-related manifestations (muscle weakness, myotonia, early onset cataracts before age 50) and systemic manifestations (cerebral, endocrine, cardiac, gastrointestinal tract, uterus, skin and immunologic involvement) that vary depending on the age of onset. The very wide clinical spectrum ranges from lethal presentations in infancy to mild, late-onset disease. |

Variable manifestations include vertebral anomalies, cleft lip/palate, microphthalmia, absent nose, dysplastic ears, hearing loss, colobomas of the iris and retina and/or bifid uvula. |

Sterile multifocal osteomyelitis with periostitis and pustulosis is a rare, severe, genetic autoinflammatory syndrome characterized by usually neonatal onset of generalized neutrophilic cutaneous pustulosis and severe, recurrent, multifocal, aseptic osteomyelitis with marked periostitis, typically affecting distal ribs, long bones and vertebral bodies. High levels of acute-phase reactants (with no fever associated) and onychosis are frequently observed additional features. |

A rare, genetic, ectodermal dysplasia syndrome characterized by corneal epithelial changes (ranging from roughening to nodular irregularities), diffuse palmoplantar hyperkeratosis with thickened, erythematous, scaly lesions affecting the elbows, knees and knuckles, distal onycholysis, brachydactyly accompanied by a single transverse palmar crease, short stature, premature birth, and increased susceptibility to tooth decay. Ocular symptoms include photophobia, reduced night vision, burning and watery eyes, and varying visual acuity. There have been no further descriptions in the literature since 1984. |

Steroid-responsive encephalopathy associated with autoimmune thyroiditis (SREAT) is a rare, acquired, neurological disease characterized by encephalopathy associated with elevated antithyroid antibodies, in the absence of other causes. Clinical presentation varies from minor cognitive impairment to status epilepticus and coma, and frequently includes seizures, confusion, speech disorder, memory impairment, ataxia and psychiatric manifestations. |

A limited form of Stevens-Johnson syndrome/toxic epidermal necrolysis spectrum characterised by destruction and detachment of the skin epithelium, involving less than 10% of the body surface area, and mucous membranes. Onset usually occurs 4-28 days after administration of the causal medication and is most frequently associated with anticonvulsants, antibacterial sulfonamides, allopurinol, nevirapine, and oxicams (non-steroidal anti-inflammatory drugs), but many other medications have also been implicated. The disease is not induced by medication in 15% of cases. Histology is characterised by an epidermal necrolysis. Multiple disabling long-term sequelae (especially cutaneous, ocular and psychological) are frequent. |
