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

Classification made for transcript

Verdict is Benign. Variant got -19 ACMG points.

PP2

Missense variant in gene, where missense usually causes diseases (based on misZ statistic), SETD2. . Gene score misZ 3.0459 (greater than the threshold 3.09). Trascript score misZ 4.1385 (greater than threshold 3.09). GenCC has associacion of gene with SETD2-related neurodevelopmental disorder without or with macrocephaly/overgrowth, Luscan-Lumish syndrome, Rabin-Pappas syndrome, SETD2-related microcephaly-severe intellectual disability-multiple congenital anomalies syndrome, Sotos syndrome.

BP4

Computational evidence support a benign effect (MetaRNN=0.004305482).

BP6

Variant 3-47057098-A-C is Benign according to our data. Variant chr3-47057098-A-C is described in ClinVar as [Likely_benign]. Clinvar id is 475535.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr3-47057098-A-C is described in Lovd as [Benign].

BS1

Variant frequency is greater than expected in population sas. gnomad4 allele frequency = 0.000735 (112/152366) while in subpopulation SAS AF= 0.0224 (108/4828). AF 95% confidence interval is 0.019.
