Genes affected

NSD3 (HGNC:12767): (nuclear receptor binding SET domain protein 3) This gene is related to the Wolf-Hirschhorn syndrome candidate-1 gene and encodes a protein with PWWP (proline-tryptophan-tryptophan-proline) domains. This protein methylates histone H3 at lysine residues 4 and 27, which represses gene transcription. Two alternatively spliced variants have been described. [provided by RefSeq, May 2015]

The c.2518G>A (p.V840I) alteration is located in exon 14 (coding exon 13) of the WHSC1L1 gene. This alteration results from a G to A substitution at nucleotide position 2518, causing the valine (V) at amino acid position 840 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
