Clinical Characteristics

Main clinical features of PEBEL1
Children with PEBEL1 are generally born healthy.

PEBEL1 is commonly triggered by illness, fever, upper respiratory tract infection, other infections or trauma/ injury. Adult-onset cases have been triggered by alcohol or cannabinoid consumption, and in the related disease, PEBEL2, by head injury.

Children will commonly have some or all of these clinical presentations:
•    Lack of muscle co-ordination (ataxia)
•    Neurological deterioration or decline, progressing rapidly.
•    Eye problems, visual disturbances.
•    Low muscle tone with floppiness (hypotonia), poor head control, reduction in movement control, tremor, shallow breathing, loss of speech and feeding are common symptoms
•    Skin blisters or burn-like rashes, particularly in areas of high movement or friction such as arm folds, neck, buttocks, fingers.
•    Seizures or fits
•    Muscle weakness
•    Numbness or pain (neuropathy)
•    Behavioural changes including confusion, psychosis and lack of interest.

The majority of cases are fatal.
