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_benign. Variant got -5 ACMG points.

• 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.
• BP4: Computational evidence support a benign effect (MetaRNN=0.2375558).
• BS2: High AC in GnomAdExome4 at 48 AD gene.

This sequence change replaces leucine with proline at codon 2350 of the NSD1 protein (p.Leu2350Pro). The leucine residue is weakly conserved and there is a moderate physicochemical difference between leucine and proline. This variant is present in population databases (rs750785772, ExAC 0.05%). This variant has not been reported in the literature in individuals affected with NSD1-related conditions. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C0"). In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
