This is the first study to tie ALS, also known as Lou Gehrig’s disease, to genetic variants associated with other degenerative brain disorders, the researchers noted. For the study, researchers analyzed the genetics of 791 people with ALS and 757 healthy people, looking for the presence of 1...
Although many genes have been identified that are mutated in ALS with many more implicated in the disease, the genetic cause for a large proportion of ALS risk remains to be discovered. The underlying biological mechanisms that converge on ALS are only partially understood but it is likely that...
There are two forms of the disorder: when it affects more than one person in the same family, the disease is called familial ALS. If no such family history exists, the patient has sporadic ALS. Genetic, environmental, and lifestyle factors all are believed to play a role in causing ALS....
Experts don't know the exact cause of ALS. About 5% to 10% of cases appear to have a genetic link, according to the National Institutes of Health . Most cases are sporadic, the NIH said. The average life expectancy with the disease is 2 to 5 years. Most patients die from respiratory...
It is also known asLou Gehrig's disease, for the legendary New York Yankees player who was stricken with it in the late 1930s. "ALS may be considered a rare disease, but it's actually more common than people think, affecting 1 in 300 Americans. It can strike anyone at anytime and ...
genetic tests, to look for disease-associated mutations blood or urine tests, to check for other potential causes of symptoms.Types of ALSALS is commonly classified into two main types, familial and sporadic, based on whether or not the person has a family history of the disease.Disease...
ALS(amytrophic lateral sclerosis) or Lou Gehrig’s disease is a degenerative medical condition which affects the brain as well as the spinal cord. It leads to loss of control of the voluntary muscles of the body. The parts most often affected are the nerves that control the speech, swallowin...
However, no animal model fully replicates the spectrum of phenotypes in the human disease and it is difficult to assess how a therapeutic effect in disease models can predict efficacy in humans. Importantly, the genetic and phenotypic heterogeneity of ALS leads to a variety of responses to ...
A:We don't know yet. Some people with ALS have been found to have the gene that causes the disease, but it accounts for only 5 to 10 percent of all ALS patients. In Korea, the proportion of people with ALS caused by genetic mutations is also low compared to other countries, at less...
Some inherent traits, most caused by genetic variants known to contribute to ALS, may influence disease risk. Age and sex ALS can develop in people of any age, but it is more common with increasing age. Most people who develop ALS do so between the ages of 55 and 75, although there ...
