Variant summary

Our verdict is Pathogenic. Variant got 10 ACMG points: 10P and 0B. PM1PM2PM5PP2PP3_ModeratePP5

The NM_022455.5(NSD1):c.5741G>A(p.Arg1914His) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.000000684 in 1,461,886 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. 13/21 in silico tools predict a damaging outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R1914C) has been classified as Pathogenic.

Genes affected

NSD1 (HGNC:14234): (nuclear receptor binding SET domain protein 1) This gene encodes a protein containing a SET domain, 2 LXXLL motifs, 3 nuclear translocation signals (NLSs), 4 plant homeodomain (PHD) finger regions, and a proline-rich region. The encoded protein enhances androgen receptor (AR) transactivation, and this enhancement can be increased further in the presence of other androgen receptor associated coregulators. This protein may act as a nucleus-localized, basic transcriptional factor and also as a bifunctional transcriptional regulator. Mutations of this gene have been associated with Sotos syndrome and Weaver syndrome. One version of childhood acute myeloid leukemia is the result of a cryptic translocation with the breakpoints occurring within nuclear receptor-binding Su-var, enhancer of zeste, and trithorax domain protein 1 on chromosome 5 and nucleoporin, 98-kd on chromosome 11. Multiple transcript variants encoding distinct isoforms have been identified for this gene. [provided by RefSeq, Sep 2018]

The variant is absent from the gnomAD v2.1.1 dataset. Different pathogenic amino acid change has been reported with sufficient evidence at the same codon (ClinVar ID: VCV000159375,VCV000159376,PMID:15452385). In silico prediction tools and conservation analysis predicted that this variant was probably damaging to the protein structure/function (REVEL: 0.817>=0.6, 3CNET: 0.998>=0.75). Therefore, this variant is classified as likely pathogenic according to the recommendation of ACMG/AMP guideline. -
