Microphthalmia-retinitis pigmentosa-foveoschisis-optic disc drusen syndrome is a rare, genetic, non-syndromic developmental defect of the eye disorder characterized by the association of posterior microphthalmia, retinal dystrophy compatible with retinitis pigmentosa, localized foveal schisis and optic disc drusen. Patients present high hyperopia, usually adult-onset progressive nyctalopia and reduced visual acuity, and, on occasion, acute-angle glaucoma. |

Autosomal recessive spastic paraplegia type 27 is a rare, pure or complex hereditary spastic paraplegia characterized by a variable onset of slowly progressive lower limb spasticity, hyperreflexia and extensor plantar responses, that may be associated with sensorimotor polyneuropathy, decreased vibration sense, lower limb distal muscle wasting, dysarthria and mild to moderate intellectual disability. |

A form of Ehlers-Danlos syndrome characterized by generalized joint hypermobility, skin hyperextensibility and easy bruising without atrophic scarring. Other common features include foot and hand deformities (piezogenic papules, pes planus, broad forefeet, brachydactyly, fragile and thin hand skin breaks or bruises easily), severe fatigue and neuromuscular symptoms including muscle weakness and myalgia. |

A rare, genetic, systemic autoimmune disease characterized by failure to thrive, global developmental delay, distinctive craniofacial dysmorphism (relative macrocephaly, dolichocephaly, frontal bossing, orbital proptosis, flattened midface with a prominent occiput, low, posteriorly rotated ears, micrognathia), hepato- and/or splenomegaly, and multisystemic autoimmune disease involving the lungs, liver, gut and/or thyroid gland. |

A rare genetic primary immunodeficiency characterized by profound circulating monocytopenia, B- and NK-cell lymphopenia and severe dendritic cell decrease, which manifests clinically with disseminated mycobacterial and viral infections, as well as opportunistic fungal and parasitic infections and frequent pulmonary alveolar proteinosis. Predisposition to developing myeloid neoplasms is associated. |

A rare, genetic, lethal, multiple congenital anomalies/dysmorphic syndrome characterized by failure to thrive, severe developmental delay, severe postnatal microcephaly, frequent congenital cardiac defects and characteristic facial dysmorphism (including coarse face with anteverted nostrils, thin vermillion, prominent alveolar ridge and retro- or micrognathia). Additional common features include neurologic abnormalities (hyper-/hypotonia, sensorineural deafness, hydrocephalus, cerebral atrophy, seizures), as well as brachydactyly, cutis marmorata and genital anomalies. |

A rare partial autosomal microdeletion syndrome characterized by neonatal hypotonia, prenatal and postnatal growth deficiency, severe feeding difficulties, global developmental delay and intellectual disability, dental anomalies (delayed tooth eruption, delayed loss of primary teeth, dental crowding), recurrent respiratory infections, thrombocytopenia and facial dysmorphism (flat facial profile, medially sparse eyebrows, epicanthal folds, flat nasal bridge and tip, short philtrum). Behavioral abnormalities (ADHD, Asperger syndrome) have also been reported. |

A rare, hereditary, developmental defect with connective tissue involvement characterized by cutis laxa of variable severity, in utero growth restriction, congenital hip dislocation and joint hyperlaxity, wrinkling of the skin, in particular the dorsum of hands and feet, and progeroid facial features. Hypotonia, developmental delay, and intellectual disability are common. In addition, cataracts, corneal clouding, wormian bones, lipodystrophy and osteopenia have been reported. |
