Variant summary

Our verdict is Benign. Variant got -14 ACMG points: 0P and 14B. BP4_StrongBP6BP7BS1BS2

The NM_003482.4(KMT2D):c.10233C>T(p.Asp3411Asp) variant causes a splice region, synonymous change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00142 in 1,613,976 control chromosomes in the GnomAD database, including 3 homozygotes. In-silico tool predicts a benign outcome for this variant. 3/3 splice prediction tools predict no significant impact on normal splicing. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars).

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]

Computational evidence support a benign effect (BayesDel_noAF=-0.56).

BP6

Variant 12-49034934-G-A is Benign according to our data. Variant chr12-49034934-G-A is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 196955.We mark this variant Likely_benign, oryginal submissions are: {Uncertain_significance=1, Benign=3, Likely_benign=5}. Variant chr12-49034934-G-A is described in Lovd as [Likely_benign].

BP7

Synonymous conserved (PhyloP=1.08 with no splicing effect.

BS1

Variant frequency is greater than expected in population nfe. gnomad4 allele frequency = 0.00103 (157/152324) while in subpopulation NFE AF= 0.00168 (114/68040). AF 95% confidence interval is 0.00143. There are 0 homozygotes in gnomad4. There are 71 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.

BS2

High AC in GnomAd4 at 157 AD gene.
