If a person in the family with ALS has a negative genetic test result (no identified genetic mutation), testing family members without a diagnosis of ALS will not provide more information. If no one in the family with ALS is available for genetic testing, a negative test result in an unaffected person cannot be interpreted.
Sporadic and familial ALS. Approximately 90% cases of ALS are called “sporadic,” meaning the cause or causes of the disease are unknown. Approximately 5-10% of cases are due to genetic mutations and are inherited from a family member. If there are two or more family members with ALS, the disease is considered familial.
There are many different types of ALS; these types are distinguished by their signs and symptoms and their genetic cause or lack of clear genetic association. Most people with ALS have a form of the condition that is described as sporadic, which means it occurs in people with no apparent history of the disorder in their family.
Familial ALS is where there is a genetic component. This means there is a gene that predisposes a person to the disease which is handed down from an ancestor who may have also suffered from it. Sporadic ALS basically covers every other form of the disease. It simply means there is no genetic component and ALS can occur for a variety of reasons.
Genetic influences on ALS. The term "familial" ALS means that there is more than one occurrence of the disease in a family. The term "sporadic" applies when there is no known history of other family members with the disease. The term "genetic" can apply to both familial and sporadic ALS. In some sporadic cases, the family history may not be known.
Up to 90 percent of people with amyotrophic lateral sclerosis (ALS) report that they have no family history of the disease. Now, new research has found approximately 17 percent of such ALS cases may be caused by a gene mutation, according to a study published in the June 21, 2017, online issue of Neurology ®,...
Research on amyotrophic lateral sclerosis has focused on animal models of the disease, its mechanisms, ways to diagnose and track it, and treatments.
Superoxide dismutase Cu-Zn also known as superoxide dismutase 1 or SOD1 is an enzyme that in humans is encoded by the SOD1 gene, located on chromosome 21. SOD1 is one of three human superoxide dismutases. It is implicated in apoptosis and amyotrophic lateral sclerosis.
Amyotrophic lateral sclerosis (ALS), also known as motor neurone disease (MND) or Lou Gehrig's disease, is a specific disease which causes the death of neurons controlling voluntary muscles. Some also use the term motor neuron disease for a group of conditions of which ALS is the most common. ALS is characterized by stiff muscles, muscle twitching, and gradually worsening weakness due to muscles decreasing in size. This results in difficulty speaking, swallowing, and eventually breathing. The cause is not known in 90% to 95% of cases. The remaining 5–10% of cases are inherited from a person's parents. About half of these genetic cases are due to one of two specific genes. The underlying mechanism involves damage to both upper and lower motor neurons. The diagnosis is based on a person's signs and symptoms, with testing done to rule out other potential causes. No cure for ALS is known. A medication called riluzole may extend life by about two to three months. Non-invasive ventilation may result in both improved quality and length of life. The disease can affect people of any age, but usually starts around the age of 60 and in inherited cases around the age of 50. The average survival from onset to death is two to four years. About 10% survive longer than 10 years. Most die from respiratory failure. In much of the world, rates of ALS are unknown. In Europe the disease affects about two to three people per 100,000 per year. Descriptions of the disease date back to at least 1824 by Charles Bell. In 1869, the connection between the symptoms and the underlying neurological problems was first described by Jean-Martin Charcot, who in 1874 began using the term amyotrophic lateral sclerosis. It became well known in the United States in the 20th century when in 1939 it affected the baseball player Lou Gehrig and later worldwide following the 1963 diagnosis of cosmologist Stephen Hawking. In 2014, videos of the Ice Bucket Challenge went viral on the Internet and increased public awareness of the condition.
