Genes affected

DNMT3A (HGNC:2978): (DNA methyltransferase 3 alpha) 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 that is thought to function in de novo methylation, rather than maintenance methylation. The protein localizes to the cytoplasm and nucleus and its expression is developmentally regulated. [provided by RefSeq, Mar 2016]

ACMG classification

Classification made for transcript

Verdict is Benign. Variant got -7 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.04468721).

BP6

Variant 2-25300185-G-A is Benign according to our data. Variant chr2-25300185-G-A is described in ClinVar as [Likely_benign]. Clinvar id is 133983.Status of the report is criteria_provided_single_submitter, 1 stars.

BS2

High AC in GnomAd4 at 20 AD gene. Variant has AC lower than other variant known as pathogenic in the gene, so the strength is limited to Supporting.

Significance: Uncertain significance

Review Status: no assertion criteria provided

Collection Method: clinical testing

The DNMT3A c.131C>T variant is predicted to result in the amino acid substitution p.Thr44Met. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.075% of alleles in individuals of East Asian descent in gnomAD. Although we suspect that this variant may be benign, at this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
