Özet

Introduction: Weaver syndrome (WS) is a rare autosomal dominant disorder characterized by distinctive facial features, pre- and post-natal overgrowth, macrocephaly, and variable developmental delay. The characteristic facial features are ocular hypertelorism, a broad forehead, almond-shaped palpebral fissures and, in early childhood, large, fleshy ears, a pointed “stuck-on” chin with horizontal skin creases, and retrognathia. Heterozygous pathogenic/likely pathogenic variants in the enhancer of zeste homolog 2 (EZH2) gene are responsible for WS. Case Presentation: Here, we report a male patient with a heterozygous likely pathogenic variant in EZH2 gene who has tall stature, distinctive facial features, mild development delay, hypoxic-ischemic encephalopathy with a MRI finding of periventricular leukomalacia, gingival hypertrophy, and early onset high hypermetropia. Conclusion: This case demonstrates the importance of reporting detailed molecular and clinical findings in patients to expand the genotypic and phenotypic findings of this rare syndrome.
