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]

ACMG classification

Verdict is Pathogenic. Variant got 17 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
• PP2: Missense variant in the NSD1 gene, where missense mutations are typically associated with disease (based on misZ statistic). The gene has 137 curated pathogenic missense variants (we use a threshold of 10). The gene has 153 curated benign missense variants. Gene score misZ: 3.4113 (above the threshold of 3.09). Trascript score misZ: 5.7368 (above the threshold of 3.09). GenCC associations: The gene is linked to Beckwith-Wiedemann syndrome, Weaver syndrome, Sotos syndrome 1, Sotos syndrome.
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.978
• PP5: Variant 5-177282523-G-A is Pathogenic according to our data. Variant chr5-177282523-G-A is described in ClinVar as [Pathogenic]. Clinvar id is 159390.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

Variant summary: NSD1 c.5951G>A (p.Arg1984Gln) results in a conservative amino acid change located in the SET domain (IPR001214) of the encoded protein sequence. Four of five in-silico tools predict a damaging effect of the variant on protein function. The variant was absent in 251304 control chromosomes (gnomAD). c.5951G>A has been reported in the literature in individuals affected with Sotos Syndrome, including one de novo occurrence (Tatton-Brown_2005, Lu_2017). These data indicate that the variant is likely to be associated with disease. At least two publication report experimental evidence evaluating an impact on protein function and this variant results in completely lost its ability to methylate H3 (Qiao_2010, Kudithipudi_2014). The following publications have been ascertained in the context of this evaluation (PMID: 27834868, 24412544, 29142766, 21196496, 15942875). ClinVar contains an entry for this variant (Variation ID: 159390). Based on the evidence outlined above, the variant was classified as pathogenic. -

Significance: Pathogenic

Review Status: criteria provided, single submitter

Collection Method: clinical testing

For these reasons, this variant has been classified as Pathogenic. Experimental studies have shown that this missense change affects NSD1 function (PMID: 21196496, 24412544, 27834868). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt NSD1 protein function. ClinVar contains an entry for this variant (Variation ID: 159390). This missense change has been observed in individual(s) with Sotos syndrome (PMID: 12807965, 15942875, 16247291, 17561922, 17565729). In at least one individual the variant was observed to be de novo. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 1984 of the NSD1 protein (p.Arg1984Gln). -
