Variant summary

Our verdict is Benign. The variant received -18 ACMG points: 0P and 18B. BP4_ModerateBP6_Very_StrongBS1BS2

The NM_003482.4(KMT2D):c.10256A>G(p.Asp3419Gly) variant causes a missense change. The variant allele was found at a frequency of 0.00208 in 1,614,010 control chromosomes in the GnomAD database, including 12 homozygotes. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Likely benign (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. D3419Y) has been classified as Likely benign.

Genes affected

KMT2D (HGNC:7133): (lysine methyltransferase 2D) The protein encoded by this gene is a histone methyltransferase that methylates the Lys-4 position of histone H3. The encoded protein is part of a large protein complex called ASCOM, which has been shown to be a transcriptional regulator of the beta-globin and estrogen receptor genes. Mutations in this gene have been shown to be a cause of Kabuki syndrome. [provided by RefSeq, Oct 2010]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -18 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.10451919).

BP6

Variant 12-49034911-T-C is Benign according to our data. Variant chr12-49034911-T-C is described in ClinVar as Benign/Likely_benign. ClinVar VariationId is 94136.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

BS1

Variant frequency is greater than expected in population nfe. GnomAd4 allele frequency = 0.00152 (231/152322) while in subpopulation NFE AF = 0.0024 (163/68034). AF 95% confidence interval is 0.0021. There are 1 homozygotes in GnomAd4. There are 117 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.

BS2

High AC in GnomAd4 at 231 AD gene.
