Variant summary

Our verdict is Likely pathogenic. Variant got 9 ACMG points: 9P and 0B. PM1 PM2 PM5 PP2 PP3_Moderate

The NM_022455.5(NSD1):​c.5854C>G​(p.Arg1952Gly) variant causes a missense change. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R1952W) has been classified as Pathogenic.

• Frequency: Genomes: not found (cov: 32)
• Consequence: NSD1 NM_022455.5 missense
• Clinical Significance: Not reported in ClinVar

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]

NSD1 (HGNC:):

ACMG classification

Verdict is Likely_pathogenic. Variant got 9 ACMG points.

• PM1: In a domain SET (size 117) in uniprot entity NSD1_HUMAN there are 17 pathogenic changes around while only 0 benign (100%) in NM_022455.5
• PM2: Very rare variant in population databases, with high coverage
• PM5: Other missense variant is known to change same aminoacid residue: Variant chr5-177280796-C-T is described in Lovd as [Pathogenic].
• PP2: Missense variant in gene, where missense usually causes diseases (based on misZ statistic), NSD1. . Gene score misZ 3.4113 (greater than the threshold 3.09). Trascript score misZ 5.7368 (greater than threshold 3.09). GenCC has associacion of gene with Beckwith-Wiedemann syndrome, Weaver syndrome, Sotos syndrome 1, Sotos syndrome.
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.852
