Description

Scientific background

A potential differential diagnosis to Sotos syndrome might be Weaver syndrome (WVS; OMIM 277590), a rare autosomal dominant disorder characterized by tall stature, variable intelligence impairment, and characteristic facial dysmorphia. Pathogenic variants in the EZH2 gene (enhancer of zeste, Drosophila, homolog 2; OMIM 601573) have been found to be causative for a large number of Weaver syndrome cases. However, genetic heterogeneity cannot be excluded.
