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.3869C>T (p.S1290L) alteration is located in exon 23 (coding exon 22) of the WHSC1L1 gene. This alteration results from a C to T substitution at nucleotide position 3869, causing the serine (S) at amino acid position 1290 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
