Consensus-based follow-up and treatment registry for GNAO1-associated disorder.

Larissa R Heideman, Nicole I Wolf, Moritz Thiel and 7 others

PMID 41689302

WHAT IT FOUND

Experts and parents agreed on 17 domains and 26 tools to track GNAO1 disorder, prioritizing communication, mobility, and social-emotional function.

This consensus framework guides future registries but does not test treatments or prove any specific tool works.

Key findings

01The panel strongly recommended including communication, mobility, and social-emotional functioning domains in the registry.

02Consensus was reached on 17 domains and 26 assessment instruments, though agreement on specific tools was lower than on domains.

03Care burden was recommended as a domain, but no validated instruments were identified in the initial search, leading to a proposal of alternatives without consensus voting.

What it does not show

The study does not test any treatments or outcomes, so it provides no evidence of efficacy for any intervention. Many proposed assessment instruments are not validated for children with GNAO1-associated disorder. The panel had limited representation from certain professions, such as only one physiotherapist, preventing analysis of profession-specific views. Two instruments were missed in the initial search and thus not voted on by the panel. No additional voting rounds were held for newly proposed instruments, which may have limited the number of consensus recommendations.

Declared interests

The study was funded by the ForWishdom Foundation. No other conflicts of interest were reported.

The easy way to misread this

Do not interpret the recommendation of assessment domains as evidence that any specific therapy or intervention works for GNAO1-associated disorder. This study only establishes what should be measured in a registry, not what treatment is effective.
