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 Benign. Variant got -11 ACMG points.

• 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.
• BP4: Computational evidence support a benign effect (MetaRNN=0.2375558).
• BP6: Variant 5-177294417-T-C is Benign according to our data. Variant chr5-177294417-T-C is described in ClinVar as [Likely_benign]. Clinvar id is 524693.Status of the report is criteria_provided_single_submitter, 1 stars.
• BS1: Variant frequency is greater than expected in population sas. gnomad4_exome allele frequency = 0.0000328 (48/1461890) while in subpopulation SAS AF= 0.000359 (31/86258). AF 95% confidence interval is 0.00026. There are 0 homozygotes in gnomad4_exome. There are 38 alleles in male gnomad4_exome subpopulation. Median coverage is 34. This position pass quality control queck.
• BS2: High AC in GnomAdExome4 at 48 AD gene.
