My daughter (7 yrs) blood test of antiglutamic acid decarboxylase (gad) is 54.000 iu/ml, what does it mean? is there a way to stop its function?

Biochemistry: Gad is an enzyme that your body needs to make the neurotransmitter gaba. If this was drown in a child, i suspect that they are considering a spinocerebellar ataxia syndrome (sca) or hyperekplexia. These are complicated and rare disorders. Your child may need to a see a child neurologist with some expertise in neuromuscular disorders if anything unusual is being considered.
