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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 07, 2024The c.3718G>A (p.D1240N) alteration is located in exon 21 (coding exon 20) of the WHSC1L1 gene. This alteration results from a G to A substitution at nucleotide position 3718, causing the aspartic acid (D) at amino acid position 1240 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
