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]

Likely benign, criteria provided, single submitter	clinical testing	Invitae	Oct 13, 2023	- -
Likely benign, no assertion criteria provided	clinical testing	Department of Pathology and Laboratory Medicine, Sinai Health System	-	The KMT2C p.P4508S variant was not identified in the literature but was identified in dbSNP (ID: rs182572555)Â¬â€ and ClinVar (submitted by ITMI, no classification provided). The variant was identified in control databases in 58 of 282632 chromosomes at a frequency of 0.0002052, and was observed at the highest frequency in the Latino population in 53 of 35436 chromosomes (freq: 0.001496) (Genome Aggregation Database March 6, 2019, v2.1.1). This frequency is greater than expected for the rare, autosomal dominant Kleefstra syndrome 2 associated with KMT2C variants. The p.P4508 residue is conserved in mammals and more distantly related organisms however computational analyses (MUT Assesor, PolyPhen-2, SIFT, MutationTaster, Revel, FATHMM, MetaLR, DANN) provide inconsistent predictions regarding the impact to the protein; this information is not very predictive of pathogenicity.Â¬â€ The variant occurs outside of the splicing consensus sequence and in silico or computational prediction software programs (Splice AI exome) do not predict a difference in splicing. In summary, based on the above information the clinical significance of this variant cannot be determined with certainty at this time although we would lean towards a more benign role for this variant. This variant is classified as likely benign. -
