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 GeneticsDec 02, 2024The c.4303G>C (p.V1435L) alteration is located in exon 24 (coding exon 23) of the WHSC1L1 gene. This alteration results from a G to C substitution at nucleotide position 4303, causing the valine (V) at amino acid position 1435 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
