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 Likely_pathogenic. Variant got 7 ACMG points.
PM1
In a domain SAM-dependent MTase C5-type (size 278) in uniprot entity DNM3B_HUMAN there are 27 pathogenic changes around while only 1 benign (96%) in NM_006892.4
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.
