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 Pathogenic. Variant got 15 ACMG points.

• PM1: In a zinc_finger_region PHD-type 4; atypical (size 47) in uniprot entity NSD1_HUMAN there are 7 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 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, 0.892
• PP5: Variant 5-177292150-G-A is Pathogenic according to our data. Variant chr5-177292150-G-A is described in ClinVar as [Likely_pathogenic]. Clinvar id is 159422.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
