Genetic Variant NSD1:p.Leu1030Ser (chr5-177211488-T-C) – ACMG Classification: Benign (-18 pts)

Variant summary

Our verdict is Benign. The variant received -18 ACMG points: 0P and 18B. BP4_ModerateBP6_Very_StrongBS1BS2

The NM_022455.5(NSD1):c.3089T>C(p.Leu1030Ser) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000119 in 1,614,138 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Likely benign (★★). Another nucleotide change resulting in the same amino acid substitution has been previously reported as Likely benign in ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. L1030F) has been classified as Likely benign.

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

Classification was made for transcript

Our verdict: Benign. The variant received -18 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.1378713).

BP6

Variant 5-177211488-T-C is Benign according to our data. Variant chr5-177211488-T-C is described in ClinVar as Benign/Likely_benign. ClinVar VariationId is 159299.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

BS1

Variant frequency is greater than expected in population nfe. GnomAdExome4 allele frequency = 0.000125 (182/1461842) while in subpopulation NFE AF = 0.000156 (174/1112000). AF 95% confidence interval is 0.000137. There are 0 homozygotes in GnomAdExome4. There are 90 alleles in the male GnomAdExome4 subpopulation. Median coverage is 37. This position passed quality control check.

BS2

High AC in GnomAd4 at 10 AD gene.
