As discussed with members of the GMS Neurology Specialist Test Group on the Webex call Thursday 8th August 2019 for Clinical Indication R59 Early onset or syndromic epilepsy: Agreed that there is enough evidence to rate this gene Green. Epilepsy is a feature of Vanishing White Matter Disorder, and therefore should include on the panel for early diagnosis in children. Promoted from Amber to Green.

Review and rating collated by Tracy Lester (Oxford Medical Genetics Laboratories Oxford University Hospitals NHS Foundation Trust, 2019_02_06) on behalf of Wessex and West Midlands GLH for GMS Neurology specialist test group, for Clinical Indication R59 'Early onset or syndromic epilepsy'. Review contributors: Alison Callaway and John Taylor. Suggested gene rating: Green.

Panel Version: 1.189
Comment on list classification: Kept rating as Amber after discussion in Genomics England Curation team. Although other EIF2B subunits are also associated with Vanishing white matter (VWM) and rated Green on the panel, there are currently insufficient clinical/literature cases of patients with EIF2B3 and seizures (1 patient in 19158808). Therefore added 'watchlist' tag while awaiting further cases.

Wu et al. (2009, PMID:19158808) analyzed 11 Chinese patients with VWM (Vanishing white matter disease) and identified variants in EIF2B3 and EIF2B5. Six patients had occassional seizures including patient 7 who had compound heterozygous variants in EIF2B3 (c.140G>A and c.1037T>C/ p.G47E, p.I346T).
