A rare genetic multiple congenital anomalies/dysmorphic syndrome characterized by developmental delay, neuropathic visceral dysmotility (resulting in neurogenic megacystis and sometimes chronic intestinal pseudo-obstruction syndrome), intracerebral calcifications, and dysmorphic facial features (including broad forehead, downslanted palpebral fissures, strabismus, protruding and low-set ears, and retrognathia). Microcephaly and renal abnormalities have also been reported. |

A rare hereditary ataxia characterized by unusual facies (i.e. gross, rough and abundant hair, mild palpebral ptosis, thick lips, and down-curved corners of the mouth), dysarthria, delayed psychomotor development, scoliosis, foot deformities, and ataxia. There have been no further descriptions in the literature since 1985. |

Hypotonia-speech impairment-severe cognitive delay syndrome is a rare, genetic neurodegenerative disorder characterized by severe, persistent hypotonia (presenting at birth or in early infancy), severe global developmental delay (with poor or absent speech, difficulty or inability to roll, sit or walk), profound intellectual disability, and failure to thrive. Additional manifestations include microcephaly, progressive peripheral spasticity, bilateral strabismus and nystagmus, constipation, and variable dysmorphic facial features (including plagiocephaly, broad forehead, small nose, low-set ears, micrognathia and open mouth with tented upper lip). |

Craniosynostosis-intracranial calcifications syndrome is a form of syndromic craniosynostosis characterized by pancraniosynostosis, head circumference below the mid-parental head circumference, mild facial dysmorphism (prominent supraorbital ridges, mild proptosis and maxillary hypoplasia) and calcification of the basal ganglia. The disease is associated with a favorable neurological outcome, normal intelligence and is inherited in an autosomal recessive manner. |

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 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. |

Multiple sclerosis-ichthyosis-factor VIII deficiency syndrome is characterized by the association of multiple sclerosis with lamellar ichthyosis and hematological anomalies (beta thalassemia minor and a quantitative deficit of factor VIII-von Willebrand complex). Other clinical manifestations may include eye involvement (optic atrophy, diplopia), neuromuscular involvement (ataxia, pyramidal syndrome, gait disturbance) and sensory disorder. There have been no further descriptions in the literature since 1992. |

Bonnemann-Meinecke-Reich syndrome is a syndrome of multiple congenital anomalies characterized by an encephalopathy which predominantly occurs in the first year of life and presenting as psychomotor delay. Additional features of the disease include moderate dysmorphia, craniosynostosis, dwarfism (due to growth hormone deficiency), intellectual disability, spasticity, ataxia, retinal degeneration, and adrenal and uterine hypoplasia. The disease has been described in only two families, with each family having two affected siblings. An autosomal recessive inheritance has been suggested. There have been no further descriptions in the literature since 1991. |

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). |

Infantile cerebral and cerebellar atrophy with postnatal progressive microcephaly is a rare, central nervous system malformation syndrome characterized by progressive microcephaly with profound motor delay and intellectual disability, associated with hypertonia, spasticity, clonus, and seizures, with brain imaging revealing severe cerebral and cerebellar atrophy, and poor myelination. |

A rare, genetic, developmental defect during embryogenesis syndrome characterized by generalized keratosis follicularis, severe proportionate dwarfism and cerebral atrophy. Alopecia (of scalp, eyebrows and eyelashes) and microcephaly are additionally observed features. Intellectual disability, inguinal hernia and epilepsy may also be associated. There have been no further descriptions in the literature since 1974. |

A rare developmental defect during embryogenesis caused by homozygous mutations in the PCNA gene and characterized by neurodegeneration, postnatal growth retardation, prelingual sensorineural hearing loss, premature aging, ocular and cutaneous telangiectasia, learning difficulties, photophobia, and photosensitivity with evidence of predisposition to sun-induced malignancy. Progressive neurologic deterioration leads to gait disturbances, muscle weakness, speech and swallowing difficulties and progressive cognitive decline. |
