Limited data capture on reproductive medicine use in amyotrophic lateral sclerosis: implications for monitoring access.

There is very limited evidence around the use of reproductive genetic testing in individuals with amyotrophic lateral sclerosis (ALS)-linked gene variants. This study aimed to identify the use of reproductive genetic testing in these individuals to understand patterns of (under)utilization and to identify barriers to equitable access. Freedom of information requests were sent in January 2025 to the 22 regional clinical genetics centers across the UK around reproductive services for individuals with, or at risk for, ALS and Huntington's disease. Limited data were available with only six trusts answering in full. The data that our study yielded raises significant concerns and inconsistencies regarding clinical recording and reporting of reproductive genetic counseling and testing. The absence of standardized retrievable data limits the ability to assess utilization and may point toward a systemic issue in data capture of reproductive genetic services for individuals at risk of ALS, and by extension, those affected by other genetic conditions.
