Genes affected

DNMT3B (HGNC:2979): (DNA methyltransferase 3 beta) CpG methylation is an epigenetic modification that is important for embryonic development, imprinting, and X-chromosome inactivation. Studies in mice have demonstrated that DNA methylation is required for mammalian development. This gene encodes a DNA methyltransferase which is thought to function in de novo methylation, rather than maintenance methylation. The protein localizes primarily to the nucleus and its expression is developmentally regulated. Mutations in this gene cause the immunodeficiency-centromeric instability-facial anomalies (ICF) syndrome. Eight alternatively spliced transcript variants have been described. The full length sequences of variants 4 and 5 have not been determined. [provided by RefSeq, May 2011]

ACMG classification

Classification made for transcript

Verdict is Benign. Variant got -7 ACMG points.

PM2

Very rare variant in population databases, with high coverage;

PP2

Missense variant in the DNMT3B gene, where missense mutations are typically associated with disease (based on misZ statistic). The gene has 15 curated pathogenic missense variants (we use a threshold of 10). The gene has 33 curated benign missense variants. Gene score misZ: 1.5 (below the threshold of 3.09). Trascript score misZ: 3.3234 (above the threshold of 3.09). GenCC associations: The gene is linked to immunodeficiency-centromeric instability-facial anomalies syndrome, immunodeficiency-centromeric instability-facial anomalies syndrome 1.

BP4

Computational evidence support a benign effect (MetaRNN=0.0063634217).

BP6

Variant 20-32787362-G-A is Benign according to our data. Variant chr20-32787362-G-A is described in ClinVar as [Likely_benign]. Clinvar id is 461483.Status of the report is criteria_provided_single_submitter, 1 stars.

BS1

Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.000433 (66/152316) while in subpopulation AFR AF= 0.00156 (65/41572). AF 95% confidence interval is 0.00126. There are 0 homozygotes in gnomad4. There are 24 alleles in male gnomad4 subpopulation. Median coverage is 33. This position pass quality control queck.
