Recently Human overgrowth syndrome-causing mutations in the gene EED have been identified.
From abstract (unpublished) Tatton-Brown et al (2017)(http://conf.hinxton.wellcome.ac.uk/advancedcourses/GRD2017Abstactbook.pdf) Human overgrowth syndromes (OGID) are a nebulous group of conditions with height and/or head circumference ≥ 2SD above the mean, together with additional phenotypic abnormalities, the commonest of which is intellectual disability. To explore the genetic architecture of human overgrowth syndromes and growth control, we have performed experimental and bioinformatic analyses of 710 individuals with OGID, identifying patients with OGID-causing mutations in genes including NSD1 (240 cases), EZH2 (34 cases), DNMT3A (18 cases), CHD8 (12 cases) and EED (two cases) and HIST1H1E (five cases). Other genes with OGID-causing mutations, identified in the current study, include NFIX (14 cases), GPC3 (two cases) and BRWD3 (seven cases) in addition to the genes encoding components of the PI3K/AKT pathway (PTEN (16 cases); PPP2R5D (three cases); AKT and PIK3CA (one case each).
