Variant summary

Our verdict is Likely pathogenic. Variant got 6 ACMG points: 7P and 1B. PM1PM5PP3_ModeratePP5BS2_Supporting

The NM_022552.5(DNMT3A):ā€‹c.2645G>Cā€‹(p.Arg882Pro) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.0000062 in 1,613,314 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Likely pathogenic (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R882G) has been classified as Pathogenic.

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 Likely_pathogenic. Variant got 6 ACMG points.

PM1
In a helix (size 8) in uniprot entity DNM3A_HUMAN there are 9 pathogenic changes around while only 0 benign (100%) in NM_022552.5
PM5
Other missense variant is known to change same aminoacid residue: Variant chr2-25234374-G-A is described in ClinVar as [Pathogenic]. Clinvar id is 375882.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
PP3
MetaRNN computational evidence supports a deleterious effect, 0.855
PP5
Variant 2-25234373-C-G is Pathogenic according to our data. Variant chr2-25234373-C-G is described in ClinVar as [Likely_pathogenic]. Clinvar id is 375880.Status of the report is no_assertion_criteria_provided, 0 stars.
BS2
High AC in GnomAdExome4 at 9 AD gene. Variant has AC lower than other variant known as pathogenic in the gene, so the strength is limited to Supporting.
