In 2011, mutations in the histone methyltransferase, <jats:italic>EZH2<\/jats:italic>, were shown to cause Weaver syndrome. To date, we have identified 48 individuals with <jats:italic>EZH2<\/jats:italic> mutations. The mutations were primarily missense mutations occurring throughout the gene, with some clustering in the SET domain (12\/48). Truncating mutations were uncommon (4\/48) and only identified in the final exon, after the SET domain. Through analyses of clinical data and facial photographs of <jats:italic>EZH2<\/jats:italic> mutation\u2010positive individuals, we have shown that the facial features can be subtle and the clinical diagnosis of Weaver syndrome is thus challenging, especially in older individuals. However, tall stature is very common, reported in &gt;90% of affected individuals. Intellectual disability is also common, present in \u223c80%, but is highly variable and frequently mild. Additional clinical features which may help in stratifying individuals to <jats:italic>EZH2<\/jats:italic> mutation testing include camptodactyly, soft, doughy skin, umbilical hernia, and a low, hoarse cry. Considerable phenotypic overlap between Sotos and Weaver syndromes is also evident. The identification of an <jats:italic>EZH2<\/jats:italic> mutation can therefore provide an objective means of confirming a subtle presentation of Weaver syndrome and\/or distinguishing Weaver and Sotos syndromes. As mutation testing becomes increasingly accessible and larger numbers of <jats:italic>EZH2<\/jats:italic> mutation\u2010positive individuals are identified, knowledge of the clinical spectrum and prognostic implications of <jats:italic>EZH2<\/jats:italic> mutations should improve. \u00a9 2013 Wiley Periodicals,
