Alpers disease is a progressive neurologic disorder that begins during childhood and is complicated in many instances by serious liver disease. Symptoms include increased muscle tone with exaggerated reflexes (spasticity), seizures, and loss of cognitive ability (dementia).
Is there a cure for Alpers disease?
Alport syndrome is an inherited disorder that is characterized by progressive kidney damage, hearing problems, and eye abnormalities. There is currently no cure for Alport syndrome and treatments are limited, but research is ongoing and various therapies are used to help patients manage its symptoms.
How does Alpers disease affect the mitochondria?
Alpers’ syndrome is most often caused by a genetic mistake in a gene called POLG. This gene provides the instructions needed to make a protein called polymerase gamma, which is responsible for “reading” sequences of mitochondrial DNA (mtDNA) and using them as a template to produce more mtDNA within the mitochondria.
When was Alpers disease discovered?
Its cause remained a mystery for nearly 70 years after it was first described in 1931 by Bernard Alpers. Dr. Naviaux’s team at UCSD discovered the cause of this classical mitochondrial disease and developed the first DNA test to diagnose it.
How do people get Alpers disease?
It is an autosomal recessive disease caused by mutation in the gene for the mitochondrial DNA polymerase POLG. The disease occurs in about one in 100,000 persons. Most individuals with Alpers’ disease do not show symptoms at birth and develop normally for weeks to years before the onset of symptoms.
Is mitochondrial disease fatal?
If a lot of Mitochondria in the body are affected, especially in important body organs, mitochondrial disease can be very serious and often fatal.
How do you treat Friedreich’s ataxia?
How is Friedreich’s ataxia treated?
- Braces to bolster the arms, legs, feet, or spine.
- Physical therapy.
- Speech therapy.
- Occupational therapy.
- Surgery to fix skeletal problems.
What causes Alport syndrome?
Alport syndrome is an inherited disease, which means it is passed down through families. It is caused by changes in your genes (mutations) to a protein called collagen. Collagen is important to the normal structure and function of the kidneys. Changes to collagen can also cause problems with the eyes and ears.
Can mitochondrial disease be cured?
There are no cures for mitochondrial diseases, but treatment can help reduce symptoms or slow the decline in health. Treatment varies from patient to patient and depends on the specific mitochondrial disease diagnosed and its severity.
What is Pearson syndrome?
Pearson syndrome is a severe disorder that usually begins in infancy. It causes problems with the development of blood-forming (hematopoietic) cells in the bone marrow that have the potential to develop into different types of blood cells. For this reason, Pearson syndrome is considered a bone marrow failure disorder.
What is POLG disease?
Mutations in the POLG gene are frequently responsible for an eye condition called progressive external ophthalmoplegia, another POLG-related disorder. This condition weakens the muscles that control eye movement and causes the eyelids to droop (ptosis).
How common is Barth Syndrome?
Barth syndrome affects all ethnic groups. The incidence of Barth syndrome is estimated to be 1 in 300,000 to 1 in 400,00 in United States. As of 2013, there have been 151 patients reported in the medical literature.
What is the ICD 10 CM code for Alpers disease?
G31. 81 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes.
What is myoclonic epilepsy with ragged red fibers?
Myoclonic epilepsy with ragged red fibers (MERRF) is a multisystem disorder characterized by myoclonus, which is often the first symptom, followed by generalized epilepsy, ataxia , weakness, and dementia . Symptoms usually first appear in childhood or adolescence after normal early development.
How are mitochondrial genes typically inherited?
You inherited your mitochondrial DNA from your mother, who inherited hers from her mother and so forth. Maternal inheritance also gave rise to the idea that there exists a “Mitochondrial Eve,” a woman from whom all living humans inherited their mitochondrial DNA.
Does Pfeiffer syndrome affect intelligence?
People with Type I Pfeiffer syndrome typically have normal intelligence. Types II and III of Pfeiffer syndrome are more severe. People with types II and III of Pfeiffer syndrome usually have problems with brain development. This can cause limitation of brain growth and developmental delays.
What is the life expectancy for mitochondrial disease?
A small study in children with mitochondrial disease examined the patient records of 221 children with mitochondrial disease. Of these, 14% died three to nine years after diagnosis. Five patients lived less than three years, and three patients lived longer than nine years.
At what age is mitochondrial disease diagnosed?
Mitochondrial disease diagnosis Every 30 minutes, a child is born who will develop a mitochondrial disorder .
What are three of the most common symptoms of mitochondrial disease?
The main symptoms of mitochondrial myopathy are muscle fatigue, weakness, and exercise intolerance. The severity of any of these symptoms varies greatly from one person to the next, even in the same family. In some individuals, weakness is most prominent in muscles that control movements of the eyes and eyelids.
Is there surgery for Friedreich’s ataxia?
Many people with Friedreich’s ataxia will develop curvature of the spine (scoliosis) and often require surgery to help straighten and support the spine. Foot abnormalities associated with FA such as club foot or high arches may be improved with surgical intervention.
How long can you live with ataxia?
Life expectancy is generally shorter than normal for people with hereditary ataxia, although some people can live well into their 50s, 60s or beyond. In more severe cases, the condition can be fatal in childhood or early adulthood.
Can people with Friedreich’s ataxia have children?
Results: FRDA did not appear to increase the risk of spontaneous abortion, preeclampsia, or preterm birth. Despite the sensory and proprioceptive loss that occurs in FRDA, nearly four fifths of births were vaginal. Of babies, 94.4% were discharged home with their mothers.
At what age does Alport syndrome start?
Hearing loss typically develops during late childhood or early adolescence, and most affected individuals become deaf by age 40. Alport syndrome is also characterized by specific eye changes. Symptoms.

What are the first signs of kidney disease?
Signs of Kidney Disease
- You’re more tired, have less energy or are having trouble concentrating.
- You’re having trouble sleeping.
- You have dry and itchy skin.
- You feel the need to urinate more often.
- You see blood in your urine.
- Your urine is foamy.
- You’re experiencing persistent puffiness around your eyes.
Does Alport syndrome cause weight gain?
Many Alport syndrome patients eventually progress to kidney failure and require dialysis or a kidney transplant. In such cases, maintaining a healthy diet becomes even more important. Patients undergoing peritoneal dialysis may gain unwanted weight because infusion fluid contains a carbohydrate called dextrose.
What is the most common mitochondrial disease?
Together, Leigh syndrome and MELAS are the most common mitochondrial myopathies. The prognosis of Leigh syndrome is generally poor, with survival generally being a matter of months after disease onset.
How does a person get mitochondrial disease?
Mitochondrial diseases are not contagious, and they are not caused by anything a person does. They’re caused by mutations, or changes, in genes — the cells’ blueprints for making proteins.
Does mitochondrial disease cause pain?
Chronic pain is common in patients with mitochondrial disease. Pain due to mitochondrial disease is primarily of neuropathic nature.
What is the treatment of Pearson syndrome?
Unfortunately, there is no cure for Pearson syndrome, and the goal of existing treatments is to decrease symptoms to improve quality of life. Children affected by Pearson syndrome may require frequent blood transfusions to help supply the body with healthy red blood cells.
What is the life expectancy of someone with Pearson syndrome?
Pancytopenia may occur alone or in association with hepatic failure and a renal tubulopathy leading to lactic acidosis. The projected median survival time is 4 years.
How is Pearson syndrome diagnosed?
Diagnosis of Pearson syndrome is possible through a bone marrow biopsy, a urine test, or a special stool test. Genetic testing can be completed to confirm the diagnosis. Treatment options include frequent blood transfusions, pancreatic enzyme replacement therapy, and treatment of infections.
