Key Takeaway
This study describes respiratory, cardiac, and mobility patterns in a Norwegian cohort. It cannot predict an individual's disease course.
Trial and Study Record
Norwegian LGMDR9 Cohort Study
Norwegian observational study describing FKRP-related disease epidemiology and clinical data from 101 people, published in 2023.

Why this record matters
- Ventilatory support preceded wheelchair dependency in some participants, often in relation to sleep apnea.
- The findings support attention to heart and breathing involvement across different levels of mobility.
Eligibility and participation notes
- Identified 153 genetically confirmed people for the epidemiologic component.
- Reviewed questionnaires and clinical notes for 101 people; 43 also had a clinical examination.
Limits and cautions
- The common c.826C>A variant predominated, limiting generalization to other populations and genotypes.
- Observational findings cannot establish treatment benefit or a fixed sequence of complications.

Clinical Features
FKRP-related disease can involve skeletal muscle, motor development, cardiac function, respiratory function, and in some severe congenital presentations, broader neurologic or structural findings. The pattern is variable, which is why the site treats phenotype as a spectrum.
Guide
Monitoring and Care
FKRP-related disease is usually managed through a multidisciplinary model. Monitoring is not only about neurology. Cardiology, pulmonology, sleep evaluation, rehabilitation, genetics, and practical family coordination all matter to safe long-term care.
