Als Inheritance Pattern - Since there are two copies of this chromosome, each cell carries two copies of the c9orf72 gene. For instance, the c9orf72 gene, which has been linked to als, is located on chromosome 9. More than 40 genes have been identified as being associated with either causing or increasing the risk of developing als/mnd. Web amyotrophic lateral sclerosis (als) is a progressive and uniformly fatal neurodegenerative disease. Web the field is moving away from a clear distinction between familial and sporadic als/mnd, recognizing that als/mnd exhibits a spectrum of inheritance patterns and genetic involvement. 90% als are sporadic cases with no clear genetic linkage. Web most of the time als is not inherited. In about 90% of cases, the person diagnosed is the only member of the family with the disease. Most cases are inherited in an autosomal dominant pattern, which means one copy of the altered gene in each cell is sufficient to cause the disorder. Most people with als don’t have a family history of it.

Web familial als can present at different ages and progress differently in various family members. Web the field is moving away from a clear distinction between familial and sporadic als/mnd, recognizing that als/mnd exhibits a spectrum of inheritance patterns and genetic involvement. Web the most common pattern of inheritance for familial als genetic mutations is called autosomal dominant. The pattern of inheritance varies depending on the gene involved.

Even nonfamilial cases can be linked to sporadic gene. Web the application of molecular genetic techniques to als, marked by the report in 1993 of linkage of the superoxide dismutase 1 ( sod1) gene in familial als, signaled an increasing focus on genetics in als as a means to gain insights into the pathogenesis of the disease, identify therapeutic targets and facilitate diagnosis ( 3 ). The two most common genetic causes of als, mutations in the c9orf72 gene and in the sod1 gene, are discussed below. How is the genetic test done?
