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]

The KMT2D c.8578C>T variant is predicted to result in the amino acid substitution p.Arg2860Cys. This variant has been reported in an individual with Kabuki syndrome (Faundes et al 2019. PubMed ID: 30459467) and in an individual with bilateral small kidneys (Patient B2451 in Supplementary Table S1, Connaughton DM et al 2019. PubMed ID: 30773290). This variant is reported in 0.021% of alleles in individuals of European (Non-Finnish) descent in gnomAD. At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
