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=0.004946828).

BP6

Variant 3-47122334-C-G is Benign according to our data. Variant chr3-47122334-C-G is described in ClinVar as [Likely_benign]. Clinvar id is 135228.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

BS1

Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.00208 (317/152354) while in subpopulation AFR AF= 0.00736 (306/41578). AF 95% confidence interval is 0.00668. There are 1 homozygotes in gnomad4. There are 148 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.

BS2

High AC in GnomAd4 at 317 AD gene.
