Green List (high evidence)

AD mandibulofacial dysostosis - Guion-Almedia type. Rare syndrome comprising progressive microcephaly, midface and malar hypoplasia, micrognathia, microtia, dysplastic ears, preauricular skin tags, significant dev delay and speech delay. OMIM reports seizures in some patients. Lines et al, 2012 - follow up of the patients reported by Guion-Almedia et al, 2006 and Wieczorek et al 2009 as well as an additional 7 patients with a similar phenotype (12 individuals in total) 5/12 had seizures. All had de novo het variants in or del involving EFTUD2 gene - del, fs, splicing, nonsense - consistent with haploinsufficiency. Huang et al 2016 - previous to this report, 69 individuals (64 kindreds) with mutations in EFTUD2 incl indivdiuals with cytogenetically visible chr abberations. In this paper a further 38 aff individuals belonging to 30 kindreds. Patients in this paper 9/30 had seizures and 21/77 in prev reported cases ~27%.
