Variant summary

Our verdict is Benign. Variant got -7 ACMG points: 1P and 8B. PP2BP4_StrongBS2

The NM_170606.3(KMT2C):ā€‹c.7259T>Gā€‹(p.Leu2420Arg) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000421 in 1,614,134 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 12/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as not provided (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. L2420V) has been classified as Likely benign.

Genes affected
KMT2C (HGNC:13726): (lysine methyltransferase 2C) This gene is a member of the myeloid/lymphoid or mixed-lineage leukemia (MLL) family and encodes a nuclear protein with an AT hook DNA-binding domain, a DHHC-type zinc finger, six PHD-type zinc fingers, a SET domain, a post-SET domain and a RING-type zinc finger. This protein is a member of the ASC-2/NCOA6 complex (ASCOM), which possesses histone methylation activity and is involved in transcriptional coactivation. [provided by RefSeq, Jul 2008]

ACMG classification

Classification made for transcript

Verdict is Benign. Variant got -7 ACMG points.

PP2
Missense variant in gene, where missense usually causes diseases (based on misZ statistic), KMT2C. . Gene score misZ 2.1357 (greater than the threshold 3.09). Trascript score misZ 4.2875 (greater than threshold 3.09). GenCC has associacion of gene with intellectual disability, autosomal dominant 40, syndromic intellectual disability, Kleefstra syndrome 2.
BP4
Computational evidence support a benign effect (MetaRNN=0.031086355).
BS2
High AC in GnomAdExome4 at 65 AD gene.
