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 -17 ACMG points.

BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.84).
BP6
Variant 2-25313904-G-A is Benign according to our data. Variant chr2-25313904-G-A is described in ClinVar as [Likely_benign]. Clinvar id is 434956.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
BS1
Variant frequency is greater than expected in population amr. gnomad4 allele frequency = 0.000243 (37/152230) while in subpopulation AMR AF= 0.00203 (31/15286). AF 95% confidence interval is 0.00147. There are 0 homozygotes in gnomad4. There are 23 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
BS2
High AC in GnomAd4 at 37 AD gene. Variant has AC lower than other variant known as pathogenic in the gene, so the strength is limited to Supporting.
