AR Band heterotopia. Keilar et al, 2014 - French family with 3 brothers with severe dev delay, ID 2/3 refractory epilepsy. Also reported an unrelated boy born to consng Moroccan parents with macrocehaly, congenital hydrocephalus, severe psychomotor delay and seizures.Hom/compound het variants identified - mutations co seg with disese in both families. Shaheen et al, 2017 - consang Saudi family - 4 individuals had hydrocephalus, 2 aff individuals deceased. Only have clinical info for proband who had intractable epilepsy.hom nonsense variant identified in proband also in 1 of the other aff relatives (no DNA on deceased). Mouse mutant model has seizures and sutle learning difficulties assoc with heterotopic nerons in the braIn white matter.

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: John Taylor and Helen Lord. Suggested gene rating: Green.

Panel Version: 1.189
Comment on list classification: Added EML1 as a green gene to the panel after advice from Arianna Tucci. All 3 published unrelated families (PMIDs:24859200 and 28556411) with EML1 variants display epilepsy/seizures.
Created: 24 Oct 2017, 3:31 p.m.
PMID:28556411 (Shaheen et al., 2017) identify a 3rd case: a homozygous truncating variant (NM_004434.2:c.1567C>T, p. [Arg523*]) in EML1 in a 2-year-old girl with congenital hydrocephalus, profound global developmental delay and intractable epilepsy.
Created: 24 Oct 2017, 3:28 p.m.
Upon screening of patients with cortical malformations, Kielar et al (PMID:24859200, 2014) report 3 French brothers with a compound het variant (c.481C>T, p.Arg138*, and c.796A>G, p.T243A) in EML1. Two of the brothers had epilepsy. An unrelated Moroccan boy with congenital hydrocephalus, severe psychomotor delay and seizures was homozygous for a W225R variant.

Added to EE panel on advice from Arianna Tucci and 3 published cases.
