Genes affected
KMT2A (HGNC:7132): (lysine methyltransferase 2A) This gene encodes a transcriptional coactivator that plays an essential role in regulating gene expression during early development and hematopoiesis. The encoded protein contains multiple conserved functional domains. One of these domains, the SET domain, is responsible for its histone H3 lysine 4 (H3K4) methyltransferase activity which mediates chromatin modifications associated with epigenetic transcriptional activation. This protein is processed by the enzyme Taspase 1 into two fragments, MLL-C and MLL-N. These fragments reassociate and further assemble into different multiprotein complexes that regulate the transcription of specific target genes, including many of the HOX genes. Multiple chromosomal translocations involving this gene are the cause of certain acute lymphoid leukemias and acute myeloid leukemias. Alternate splicing results in multiple transcript variants.[provided by RefSeq, Oct 2010]

ACMG classification

Classification made for transcript

Verdict is Benign. Variant got -19 ACMG points.

PP2
Missense variant in the KMT2A gene, where missense mutations are typically associated with disease (based on misZ statistic). The gene has 45 curated pathogenic missense variants (we use a threshold of 10). The gene has 124 curated benign missense variants. Gene score misZ: 6.2276 (above the threshold of 3.09). Trascript score misZ: 8.7715 (above the threshold of 3.09). GenCC associations: The gene is linked to Wiedemann-Steiner syndrome.
BP4
Computational evidence support a benign effect (MetaRNN=0.0042158663).
BP6
Variant 11-118472663-G-A is Benign according to our data. Variant chr11-118472663-G-A is described in ClinVar as [Likely_benign]. Clinvar id is 211313.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr11-118472663-G-A is described in Lovd as [Likely_benign]. Variant chr11-118472663-G-A is described in Lovd as [Benign].
BS1
Variant frequency is greater than expected in population nfe. gnomad4 allele frequency = 0.00584 (882/151030) while in subpopulation NFE AF= 0.0058 (393/67802). AF 95% confidence interval is 0.00532. There are 10 homozygotes in gnomad4. There are 511 alleles in male gnomad4 subpopulation. Median coverage is 31. This position pass quality control queck.
BS2
High AC in GnomAd4 at 882 AD gene.
