Living with Familial infantile myoclonic epilepsy
A rare genetic epilepsy that starts in newborns or infants and runs in families, with seizures and sometimes speech and balance problems.
Understanding Familial infantile myoclonic epilepsy
Seizures involve sudden jerks (myoclonic) and focal seizures, and occur in several members of a family. Some people also have mild slurred speech, balance problems (ataxia), or intellectual disability from borderline to moderate.
Signs & symptoms
Symptoms vary from person to person. GARD lists these among the most common:
- Seizures
- Sudden muscle jerks (myoclonic seizures)
- Seizures in one half of the brain (focal)
- Whole-body seizures (tonic-clonic)
- Seizures with fever (febrile)
- Slurred speech (dysarthria)
Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.
Diagnosis
- 1Talk with your doctor
Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.
- 2See a specialist
Specialists who may be involved include brain and nervous system specialists, genetic specialists and seizure and epilepsy specialists.
- 3Consider genetic testing
Changes in TBC1D24 are linked to this condition. Genetic testing and counseling can help confirm a diagnosis and explain what it means for your family.
- 4Connect with expert centers
Epilepsy Foundation may keep lists of experts for this condition.

Quick facts
Changes in the TBC1D24 gene cause it. It is autosomal recessive, which means a child inherits a changed copy of the gene from each parent.
