Living with Severe congenital nemaline myopathy
A severe muscle condition from birth with very low muscle tone, little movement, and breathing and swallowing trouble.
Understanding Severe congenital nemaline myopathy
Newborns have severe low muscle tone (hypotonia) and move very little on their own. It can bring breathing trouble, swallowing trouble, and stiff joints. Signs may start before birth, such as reduced fetal movement. It begins in the newborn and infant period.
Signs & symptoms
Symptoms vary from person to person. GARD lists these among the most common:
- Severe low muscle tone in newborns
- Little spontaneous movement
- Breathing difficulties
- Trouble swallowing
- Stiff, bent joints (contractures)
- Reduced movement before birth
Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.
