Prognosis
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]

Etiology
Prenatal testing is possible where one parent is known to be a carrier of the condition. [ 6 ] Bergemann AD, Cole F, Hirschhorn K ; The etiology of Wolf-Hirschhorn syndrome. Trends Genet. 2005 Mar21(3):188-95. [patient.info]
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]
