Variant summary

Our verdict is Benign. The variant received -13 ACMG points: 0P and 13B. BP4_Strong BP6 BS1 BS2

The NM_014159.7(SETD2):​c.2155A>G​(p.Asn719Asp) variant causes a missense change. The variant allele was found at a frequency of 0.0000743 in 1,614,178 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 Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. N719H) has been classified as Uncertain significance.

Genes affected

SETD2 (HGNC:18420): (SET domain containing 2, histone lysine methyltransferase) Huntington's disease (HD), a neurodegenerative disorder characterized by loss of striatal neurons, is caused by an expansion of a polyglutamine tract in the HD protein huntingtin. This gene encodes a protein belonging to a class of huntingtin interacting proteins characterized by WW motifs. This protein is a histone methyltransferase that is specific for lysine-36 of histone H3, and methylation of this residue is associated with active chromatin. This protein also contains a novel transcriptional activation domain and has been found associated with hyperphosphorylated RNA polymerase II. [provided by RefSeq, Aug 2008]

ACMG classification

Our verdict: Benign. The variant received -13 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.04010451).
• BP6: Variant 3-47122481-T-C is Benign according to our data. Variant chr3-47122481-T-C is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 135211.
• BS1: Variant frequency is greater than expected in population sas. GnomAd4 allele frequency = 0.000112 (17/152362) while in subpopulation SAS AF = 0.00124 (6/4832). AF 95% confidence interval is 0.000541. There are 0 homozygotes in GnomAd4. There are 11 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.
• BS2: High AC in GnomAd4 at 17 AD gene.
