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 GeneticsJan 24, 2023The c.3242T>C (p.V1081A) alteration is located in exon 19 (coding exon 18) of the WHSC1L1 gene. This alteration results from a T to C substitution at nucleotide position 3242, causing the valine (V) at amino acid position 1081 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
