Added comment: PMID: 34430430 (2021) - Case report on 1 infant with a homozygous frameshift variant and Zellweger Syndrome diagnosis. Presented with an epileptic seizure at 8 months old and focal seizures during sleep, died at 9 months old. Also described a literature review resulting in 1/4 previously reported infants with Zellweger Syndrome presenting with seizures, described below.

PMID: 28823628 (2017) - Case report on 1 infant with a homozygous missense variant and Zellweger Syndrome diagnosis. Developed tonic-clonic jerking of extremities.

GeneReviews: Seizures can be a symptom of Zellweger Syndrome in newborns (caused by underlying neuronal migration defects).
