Summaries for Leigh Syndrome

Genetics Home Reference : 25 Leigh syndrome is a severe neurological disorder that usually becomes apparent in the first year of life. This condition is characterized by progressive loss of mental and movement abilities (psychomotor regression) and typically results in death within two to three years, usually due to respiratory failure. A small number of individuals do not develop symptoms until adulthood or have symptoms that worsen more slowly. The first signs of Leigh syndrome seen in infancy are usually vomiting, diarrhea, and difficulty swallowing (dysphagia), which disrupts eating. These problems often result in an inability to grow and gain weight at the expected rate (failure to thrive). Severe muscle and movement problems are common in Leigh syndrome. Affected individuals may develop weak muscle tone (hypotonia), involuntary muscle contractions (dystonia), and problems with movement and balance (ataxia). Loss of sensation and weakness in the limbs (peripheral neuropathy), common in people with Leigh syndrome, may also make movement difficult. Several other features may occur in people with Leigh syndrome. Many individuals with this condition develop weakness or paralysis of the muscles that move the eyes (ophthalmoparesis); rapid, involuntary eye movements (nystagmus); or degeneration of the nerves that carry information from the eyes to the brain (optic atrophy). Severe breathing problems are common, and these problems can worsen until they cause acute respiratory failure. Some affected individuals develop hypertrophic cardiomyopathy, which is a thickening of the heart muscle that forces the heart to work harder to pump blood. In addition, a substance called lactate can build up in the body, and excessive amounts are often found in the blood, urine, or the fluid that surrounds and protects the brain and spinal cord (cerebrospinal fluid) of people with Leigh syndrome. The signs and symptoms of Leigh syndrome are caused in part by patches of damaged tissue (lesions) that develop in the brains of people with this condition. A medical procedure called magnetic resonance imaging (MRI) reveals characteristic lesions in certain regions of the brain. These regions include the basal ganglia, which help control movement; the cerebellum, which controls the ability to balance and coordinates movement; and the brainstem, which connects the brain to the spinal cord and controls functions such as swallowing and breathing. The brain lesions are often accompanied by loss of the myelin coating around nerves (demyelination), which reduces the ability of the nerves to activate muscles used for movement or relay sensory information from the rest of the body back to the brain.

MalaCards based summary : Leigh Syndrome, also known as leigh disease, is related to leigh syndrome with leukodystrophy and striatonigral degeneration, infantile, mitochondrial, and has symptoms including seizures, ataxia and ophthalmoplegia. An important gene associated with Leigh Syndrome is SURF1 (SURF1 Cytochrome C Oxidase Assembly Factor), and among its related pathways/superpathways are Oxidative phosphorylation and Metabolism. The drugs Sargramostim and Melphalan have been mentioned in the context of this disorder. Affiliated tissues include brain, eye and spinal cord, and related phenotypes are nystagmus and ataxia

Disease Ontology : 12 A mitochondrial metabolism disease characterized by progressive loss of mental and movement abilities. Symptoms usually begin between ages of three months and two years and include loss of appetite, vomiting, irritability and seizure activity.

NIH Rare Diseases : 53 Leigh syndrome is a rare, inherited neurodegenerative condition. It usually becomes apparent in infancy, often after a viral infection. Rarely, it begins in the teenage or adult years. Signs and symptoms usually progress rapidly. Early symptoms may include poor sucking ability; loss of head control and motor skills; loss of appetite; vomiting; and seizures. As the condition progresses, symptoms may include weakness and lack of muscle tone; spasticity; movement disorders; cerebellar ataxia; and peripheral neuropathy. Complications can lead to impairment of respiratory, heart and kidney function. The term "Leigh-like syndrome" is often used for people with features that are strongly suggestive of Leigh syndrome but who do not meet the diagnostic criteria. The inheritance of Leigh syndrome depends on where the responsible gene is located in each case. This is because it can be due to mutations in either mitochondrial DNA or nuclear DNA: Mitochondrial DNA-associated Leigh syndrome follows a mitochondrial inheritance pattern (also called maternal inheritance). Nuclear gene-encoded Leigh syndrome may be inherited in an autosomal recessive or X-linked manner. Treatment is based on the symptoms present and depends on the type of Leigh syndrome a person has. While life expectancy depends on the cause of Leigh syndrome in each person, most do not survive past mid-childhood or adolescence.

OMIM : 57 Leigh syndrome is a clinically and genetically heterogeneous disorder resulting from defective mitochondrial energy generation. It most commonly presents as a progressive and severe neurodegenerative disorder with onset within the first months or years of life, and may result in early death. Affected individuals usually show global developmental delay or developmental regression, hypotonia, ataxia, dystonia, and ophthalmologic abnormalities, such as nystagmus or optic atrophy. The neurologic features are associated with the classic findings of T2-weighted hyperintensities in the basal ganglia and/or brainstem on brain imaging. Leigh syndrome can also have detrimental multisystemic affects on the cardiac, hepatic, gastrointestinal, and renal organs. Biochemical studies in patients with Leigh syndrome tend to show increased lactate and abnormalities of mitochondrial oxidative phosphorylation. Thus, Leigh syndrome may be a clinical feature of a primary deficiency of any of the mitochondrial respiratory chain complexes: complex I deficiency (see 252010), complex II deficiency (see 252011), complex III deficiency (see 124000), complex IV deficiency (cytochrome c oxidase; see 220110), or complex V deficiency (see 604273) (summary by Lake et al., 2015). (256000)

NINDS : 54 Leigh's disease is a rare inherited neurometabolic disorder that affects the central nervous system. This progressive disorder begins in infants between the ages of three months and two years. Rarely, it occurs in teenagers and adults. Leigh's disease can be caused by mutations in mitochondrial DNA or by deficiencies of an enzyme called pyruvate dehydrogenase. Symptoms of Leigh's disease usually progress rapidly. The earliest signs may be poor sucking ability,and the loss of head control and motor skills.These symptoms may be accompanied by loss of appetite, vomiting, irritability, continuous crying, and seizures. As the disorder progresses, symptoms may also include generalized weakness, lack of muscle tone, and episodes of lactic acidosis, which can lead to impairment of respiratory and kidney function.   In Leigh’s disease, genetic mutations in mitochondrial DNA interfere with the energy sources that run cells in an area of the brain that plays a role in motor movements. The primary function of mitochondria is to convert the energy in glucose and fatty acids into a substance called adenosine triphosphate ( ATP). The energy in ATP drives virtually all of a cell's metabolic functions. Genetic mutations in mitochondrial DNA, therefore, result in a chronic lack of energy in these cells, which in turn affects the central nervous system and causes progressive degeneration of motor functions. There is also a form of Leigh’s disease (called X-linked Leigh's disease) which is the result of mutations in a gene that produces another group of substances that are important for cell metabolism. This gene is only found on the X chromosome.

KEGG : 37
Leigh syndrome is a severe neurological disorder, characterized by bilaterally symmetrical necrotic lesions in the basal ganglia and brainstem. Most frequently the central nervous system is affected, with psychomotor retardation, seizures, nystagmus, optic atrophy, ataxia, or respiratory failure. Some patients also present with peripheral nervous system involvement or non-neurologic abnormalities. In the majority of cases, dysfunction of the mitochondrial respiratory chain complex or of the pyruvate dehydrogenase complex are responsible for the disease. Patterns of inheritance include X-linked recessive, autosomal recessive, and mitochondrial.

UniProtKB/Swiss-Prot : 74 Leigh syndrome: An early-onset progressive neurodegenerative disorder characterized by the presence of focal, bilateral lesions in one or more areas of the central nervous system including the brainstem, thalamus, basal ganglia, cerebellum and spinal cord. Clinical features depend on which areas of the central nervous system are involved and include subacute onset of psychomotor retardation, hypotonia, ataxia, weakness, vision loss, eye movement abnormalities, seizures, and dysphagia.
