Abstract

Wiedemann-Steiner syndrome (WDSTS) is a very rare genetic disorder characterized by short stature, intellectual disability and distinctive facial appearance. We present a five-year-old boy who was diagnosed with WDSTS based on identification of a novel de novo pathogenic variant in the KMT2A gene (OMIM: 159555) by Whole Exome Sequencing and supported by some characteristic clinical features. Genotype and phenotype of the patient is compared with the earlier reported patients in the literature, in an attempt to broaden our knowledge of this rare syndrome.
