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=0.0054247975).
BP6
Variant 3-47124046-G-A is Benign according to our data. Variant chr3-47124046-G-A is described in ClinVar as [Likely_benign]. Clinvar id is 475528.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
BS1
Variant frequency is greater than expected in population eas. gnomad4 allele frequency = 0.000328 (50/152298) while in subpopulation EAS AF= 0.00193 (10/5182). AF 95% confidence interval is 0.00105. There are 0 homozygotes in gnomad4. There are 27 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
BS2
High AC in GnomAd4 at 50 AD gene.
