What support options are available to asymptomatic ALS gene carriers?

Genetic counseling can help you better understand your personal risk and keep you informed about new scientific findings regarding ALS genes and related studies. To this end, it is recommended that you consult a medical care center or institute for human genetics that specializes in ALS genetics. Neurological examinations conducted at longer intervals can help identify possible early signs of ALS. Guidelines regarding the appropriate time intervals and testing for the neurofilament (NfL) biomarker have not yet been adopted.

For asymptomatic carriers of the SOD1 mutation, a neurological examination and NfL analysis every twelve months are recommended. These checkups focus on detecting early signs of ALS, which are referred to as prodromal ALS. Treatment with Tofersen can be initiated as soon as early signs of ALS appear. Thus, the follow-up examination for asymptomatic carriers of a SOD1 mutation has therapeutic relevance and serves as a screening test. In some cases, there is the option to participate in research projects aimed at developing prevention and early detection strategies.
