Prognosis was poor. Eight cases died, while survived cased suffered from refractory epilepsy, profound mental retardation, muscle weakness, etc.[ncbi.nlm.nih.gov]
Prognosis Frequently results in stillbirth or death within the first year. If patients survive beyond infancy, they have slow but constant progress in terms of development.[patient.info]
Identification of the molecular basis of EIEE in an affected individual may confirm diagnosis, determine prognosis, inform treatment options, and encourage testing of additional family members to inform reproductive risk.[invitae.com]

Karyotype assessment is important to consider in all epilepsies where the etiology is uncertain as dysmorphic features may be subtle or not apparent. Karyotype examination should be extended to 50-100 mitoses to exclude mosaicism.[epilepsydiagnosis.org]
