Abstract excerpt
BACKGROUND: Rauch-Steindl syndrome (RAUST) is a rare neurodevelopmental disorder caused by pathogenic variants in NSD2, a histone methyltransferase gene at 4p16.3. Due to phenotypic overlap with Wolf-Hirschhorn syndrome (WHS), RAUST is often misdiagnosed. Missense variants in NSD2 are particularly challenging to interpret without functional validation. METHODS: Genomic DNA from the proband and her parents was...
