The article below states that the C9 mutation for example accounts for 25-40% of familial ALS. What I dont understand is it also say C9 accounts for 7% of sporadic ALS cases. It lists familial and sporadic percentages for a number of different mutations. This does not make sense to me. If the C9 mutation is found in 7% of "sporadic" ALS cases, wouldn't that mean these were actually familial?
ALS Genes and Mutations
Research has shown that about two out of three of people with familial ALS and about one out of 10 people with sporadic ALS have a mutation (or change) in at least one of the more than 40 genes linked to the disease.
