Rebecca Foulger edited their review of gene: EIF2S3: Added comment: 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. ; Changed rating: AMBER
Rebecca Foulger Added comment: Comment on list classification: Updated rating from Amber to Green: Probable rating in Gene2Phenotype for 'Syndromic ID with severe microcephaly' but sufficient unrelated cases (>3) of seizures in MEHMO patients from literature (PMIDs 23063529,27333055,28055140).
Rebecca Foulger commented on gene: EIF2S3: Skopkova et al 2017 (PMID:28055140) identified a C-terminal frameshift mutation (Ile465Serfs) in the EIF2S3 gene in three families with MEHMO syndrome and a novel maternally inherited missense EIF2S3 variant (c.324T>A; p.Ser108Arg) in another male patient with less severe clinical symptoms. Two of the families had members with seizures amongst their phenotypes.
Rebecca Foulger commented on gene: EIF2S3: Moortgat et al, 2016 (PMID:27333055) examined syndromic intellectual disability in two unrelated families with suspected X-linked inheritance. In both families, affected males presented with severe intellectual disability, microcephaly, growth retardation, and epilepsy in most individuals. A missense variant(c.777T>G p.(Ile259Met)) and a frameshift variant (c.1394_1397del p.(Ile465Serfs*4)) were identified in the EIF2S3 gene in the hemizygous state in affected patients, and in the heterozygous states female obligate carriers.
Rebecca Foulger commented on gene: EIF2S3: Borck et al., 2012 (PMID:23063529) ascertained a family of Morocco Jewish ancestry in which three male individuals were affected by X-linked intellectual disability (ID). Individual III:2 had generalized seizures.
