Exploring the needs and preferences of people with amyotrophic lateral sclerosis (ALS) when making genomic testing...

Objective: Whole Genome Sequencing (WGS) for amyotrophic lateral sclerosis (ALS) (also known as motor neuron disease, MND) raises multiple considerations and has a range of implications for individuals and their family. However, it is unclear what needs people with ALS have when making genomic testing decisions. This study explores the experiences, needs and preferences of these individuals when considering WGS and going through the process. Methods: A semi-structured interview study was carried out with 14 people with ALS from across the UK who had, or were considering, WGS. Participants were recruited from a local ALS care center and MND Association/MND Scotland channels. Data were analyzed using framework analysis. Results: Findings indicate variation in (a) how WGS and access to pretest genetic counseling is provided, (b) the perceived adequacy of information to support decision-making and prepare people with ALS for their test result and its consequences, and (c) preferences for making decisions with family and health professionals that best meets their clinical and life needs along the care pathway. Conclusions: There is an urgent need for people with ALS to have relevant, accurate and accessible information that supports proactively their decision-making around WGS, particularly in the context of genetically-targeted treatments and clinical trials. These findings will contribute to the development of a shared decision-making intervention supporting people with ALS to make genomic testing decisions with their family and neurology services.
