Variant summary

Our verdict is Likely benign. Variant got -3 ACMG points: 2P and 5B. PP2PP3BP6BS2

The NM_170606.3(KMT2C):ā€‹c.1402C>Gā€‹(p.Pro468Ala) variant causes a missense change. The variant allele was found at a frequency of 0.0000205 in 1,613,208 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 Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. P468T) 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]
