Genes affected
NSD2 (HGNC:12766): (nuclear receptor binding SET domain protein 2) This gene encodes a protein that contains four domains present in other developmental proteins: a PWWP domain, an HMG box, a SET domain, and a PHD-type zinc finger. 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. [provided by RefSeq, Jul 2008]

Pathogenic, criteria provided, single submitter | clinical testing | GeneDx | Oct 11, 2018 | The Q52X variant in the NSD2 gene has not been reported previously as a pathogenic variant nor as a benign variant, to our knowledge. This variant is predicted to cause loss of normal protein function either through protein truncation or nonsense-mediated mRNA decay. The Q52X variant is observed in 1/111,594 alleles from individuals of non-Finnish European background in large population cohorts (Lek et al., 2016). We interpret Q52X as a pathogenic variant. - |
