A rare genetic neuromuscular channelopathy characterized by normokalemic episodes of painful muscle cramping followed by progressive, permanent, flaccid weakness, triggered by stress, cold and exercise, associated with myopathic myopathy and painful acute edema with neuronal compression, foot drop and muscle degeneration when located in the tibialis anterior muscle group.	preferido
A rare genetic neuromuscular disease characterized by early onset muscular weakness with predominant proximal lower limb involvement. The disorder is static or only mildly progressive. The severity of manifestations ranges from lethal, congenital muscular atrophy with arthrogryposis to asymptomatic with subclinical features.	preferido
A rare genetic neuromuscular disease characterized by early onset of proximal or generalized muscle weakness, external ophthalmoplegia with or without ptosis, and joint contractures. Hypotonia, neonatal respiratory distress necessitating ventilation, and severe dysphagia have also been reported. The disease is of variable severity and non- or slowly progressive. Patients typically remain ambulatory. Muscle biopsy may show predominance of type 1 fibers, marked variability in fiber size, increased internal nuclei, and proliferation of perimysial and endomysial connective tissue.	preferido
A rare genetic neuromuscular disease characterized by late onset of mild, progressive, proximal muscle weakness, severe myalgias during and after exercise, and susceptibility to rhabdomyolysis. Intellectual disability is mild or absent. There are no abnormalities of the skin. Muscle biopsy shows focal depletion of mitochondria especially at the center of muscle fibers, surrounded by enlarged mitochondria at the periphery.	preferido
A rare genetic neuromuscular disease characterized by length-dependent axonal motor neuropathy predominantly affecting the lower limbs, in combination with a myopathy with morphological features of myofibrillar myopathy with aggregates and rimmed vacuoles. Age of onset is typically in the second to third decade of life. Patients present with slowly progressive muscle weakness and atrophy initially affecting the distal lower limbs and later progressing to involve proximal limbs and also truncal muscles. There is no involvement of respiratory and cardiac muscles.	preferido
A rare genetic neurovascular malformation characterized by sac-like bulging of cerebral arteries due to weakening of the endothelial layer. Familial occurrence is suspected when two or more affected first- to third-degree relatives are present in a family. Aneurysms may remain asymptomatic throughout life, or rupture and thereby cause potentially life-threatening subarachnoid hemorrhage. Patients with familial cerebral saccular aneurysm are more likely to develop more than one brain aneurysm, are at greater risk of rupture, and tend to have poorer outcome after rupture than patients with sporadic cerebral aneurysms.	preferido
A rare genetic non-syndromic central nervous system malformation characterized by absence of the telencephalon and absent or abnormal diencephalic structures, combined with severe abnormalities of the mesencephalon and cerebellum. Further malformations, for example of the hands and feet, have been described in addition.	preferido
A rare genetic ocular disease characterized by congenital nystagmus (horizontal, vertical and/or torsional), foveal hypoplasia, presenile cataracts (with typical onset in the second to third decade of life), and normal irides. Corneal pannus and/or optic nerve hypoplasia may also be present.	preferido
A rare genetic odontologic disease characterized by failure of eruption of non-ankylosed permanent teeth without evidence of obvious mechanical obstruction. Posterior teeth are preferentially affected (typically with involvement of all teeth distal to the most mesial non-erupted tooth), resulting in a posterior open bite. Non-ankylosed teeth tend to become ankylosed, and orthodontic treatment of affected teeth is generally unsuccessful.	preferido
A rare genetic parenchymatous liver disease characterized by infantile or early childhood onset of recurrent episodes of acute liver failure precipitated by a febrile illness. During the life-threatening episodes, patients present with vomiting, lethargy, jaundice, as well as elevated levels of liver enzymes and coagulopathy. There is usually complete recovery between the episodes with conservative treatment.	preferido
A rare genetic peripheral neuropathy characterized by complete congenital insensitivity to painful stimuli, commonly associated with neuropathic arthropathy. In addition, patients are typically anosmic.	preferido
A rare genetic peripheral neuropathy characterized by early hypotonia evolving to spastic paraparesis, areflexia, decreased pain and temperature sensitivity, autonomic neuropathy, gastroesophageal reflux disease, recurrent pneumonia and respiratory problems. Patients also have intellectual disability and dysmorphic features, including mild brachycephalic microcephaly, short broad neck, low anterior hairline and coarse face.	preferido
A rare genetic peripheral neuropathy characterized by recurrent, stereotyped, episodic intense pain, occurring predominantly in either the upper body or lower limbs in several members of a family, which is triggered or exacerbated by fatigue, cold exposure, fasting, weather changes and/or physical stress or exertion and may or may not diminish with age. Sweating and other manifestations, such as tachycardia, breathing difficulties and generalized pallor, may be associated.	preferido
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.	preferido
A rare genetic primary immunodeficiency due to a defect in adaptive immunity characterized by severe immunodeficiency, presenting with profound susceptibility to viral, fungal and bacterial infections due to impaired CD25-mediated T-regulatory cell function, in association with severe autoimmune disease, such as alopecia universalis, erythrodermia, and autoimmune thyroiditis and enteropathy.	preferido
A rare genetic primary lymphedema characterized by lymphedema of all four limbs with age of onset ranging from birth to adulthood. Manifestations are of variable severity, and upper limb involvement may develop only later in the disease course. Recurrent episodes of cellulitis and skin infections are observed in severe cases. Varicose veins and venous incompetence have been reported in association.	preferido
A rare genetic primary lymphedema characterized by uniform, widespread lymphedema, often with systemic involvement such as intestinal and pulmonary lymphangiectasia, pleural and pericardial effusions, and chylothorax. There is a high incidence of non-immune hydrops fetalis, which may result in fetal demise or fully resolve after birth. Severe, recurrent facial cellulitis is observed in some patients. Presence of epicanthic folds or micrognathia has occasionally been reported, while intelligence is normal, and seizures are absent.	preferido
A rare genetic primary lymphedema characterized by unilateral or bilateral lower limb lymphedema of variable severity. The condition shows almost complete penetrance with onset in childhood or adolescence in females, whereas in males it shows incomplete penetrance with later onset of disease. Lymphoscintigraphy in more severely affected individuals reveals lymphatic abnormalities consistent with lymphangiectasia, valve dysfunction, and thoracic duct reflux.	preferido
A rare genetic progressive myoclonic epilepsy characterized by childhood onset of progressive dysarthria, myoclonus, ataxia, seizures, and cognitive decline. The disease takes a protracted course with patients surviving into adulthood, developing signs and symptoms like psychosis with outbursts of prolonged agitation and screaming, spasticity and hyperreflexia, confusion, mutism, and incontinence. There are no visual disturbances. Muscle biopsy shows numerous periodic acid-Schiff-positive inclusions, so-called Lafora bodies.	preferido
A rare genetic renal tubular disease characterized by hypomagnesemia (due to renal magnesium wasting), hypokalemia and activation of renin production due to specific mitochondrial DNA mutations. Hypocalciuria, metabolic alkalosis, progressive chronic kidney disease as well as arterial hypertension and hypercholesterolemia have been reported. Tetany, tremor, paresthesia, muscle fatigue, chondrocalcinosis and cerebral seizures can be present. Extrarenal manifestations of mitochondrial dysfunction may not be evident in the patients.	preferido
