Probable histone-lysine N-methyltransferase NSD2 is an enzyme that in humans is encoded by the NSD2 gene. [5] [6] [7]
This gene encodes a protein that contains several domain types present in other developmental proteins: PWWP domains, an HMG box, a SET domains, several PHD-type zinc fingers and a terminal C5HCH motif. It is expressed ubiquitously in early development.
Wolf-Hirschhorn syndrome (WHS) is a malformation syndrome associated with a hemizygous deletion of the distal short arm of chromosome 4. This gene maps to the 165 kb WHS critical region and has also been involved in the chromosomal translocation t(4;14)(p16.3;q32.3) in multiple myelomas.
Alternative splicing of this gene results in multiple transcript variants encoding different isoforms. Some transcript variants are nonsense-mediated mRNA (NMD) decay candidates, hence not represented as reference sequences. [7]
