NSD2

Chr 4AD

nuclear receptor binding SET domain protein 2

Also known as: KMT3F, KMT3G, MMSET, RAUST, REIIBP, TRX5, WHS, WHSC1

The protein encoded by this gene is a histone methyltransferase that contains PWWP, HMG box, SET, and PHD domains and functions in chromatin modification during early development. Loss-of-function mutations cause Rauch-Steindl syndrome through an autosomal dominant inheritance pattern. The gene is also located within the Wolf-Hirschhorn syndrome critical region on chromosome 4p16.3 and contributes to the malformation phenotype seen with deletions of this chromosomal region.

Definitive — sufficient evidence for diagnostic panels

Population Constraint (gnomAD)
Highly constrained gene — heterozygous loss-of-function variants are very rare in the population (pLI 1.00). One damaged copy is likely sufficient to cause disease.
