What it is Filled
Nemaline myopathy is a clinically and genetically heterogeneous congenital structural myopathy characterized by muscle weakness of varying severity and nemaline rods on muscle biopsy, with a generally non-progressive course but variable progression and complications; acquired nemaline myopathy is outside this sense.
In scope
- The subject includes the definition and boundaries of congenital nemaline myopathy.
- Nemaline rods are interpreted alongside clinical and molecular evidence.
- Inherited disease is included, with sporadic acquired nemaline myopathy considered only to distinguish it from the subject.
- Motor, respiratory and bulbar involvement are assessed over time.
- Disease-specific evidence informs surveillance, supportive care and research eligibility.
Out of scope
- Complete patient records and unrelated comorbidities
- General models of congenital myopathy, muscular dystrophy and motor neuron disease
- Independent models of genes, variants and sarcomeric proteins
- Laboratory workflows for sequencing and muscle specimen processing
- Detailed prescribing, ventilation-device operation and rehabilitation protocols
- Independent management of monoclonal gammopathy or HIV infection
Why it exists Filled
Enable an AI agent to recognize congenital nemaline myopathy, distinguish its genetic forms and acquired mimics, assess documented functional and respiratory state, and identify evidence-supported next steps for specialist review.
Distinguishing features Filled
- A compatible muscle-weakness phenotype with nemaline bodies on muscle biopsy supports recognition of congenital nemaline myopathy, whose presentations vary in severity and age of recognition.
- A nemaline myopathy diagnosis must be distinguished from an isolated rod finding because rods can occur in other diseases and some normal muscle contexts.
- Facial, neck and proximal limb weakness form a recognizable pattern without every region necessarily being affected.
- Late recognition of inherited disease does not establish acquired disease, and sporadic acquired nemaline myopathy is a separate condition outside this model.
- Respiratory involvement requires assessment independently of limb function because walking ability alone is insufficient to characterize disease burden.

Not applicable

Context of use required Filled
- This diagnosis is encountered in neuromuscular medicine, clinical genetics and muscle pathology.
- It provides a framework for investigating muscle weakness and documenting associated functional, swallowing and respiratory difficulties.
