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]

Significance:Uncertain significance

Review Status:no assertion criteria provided

Collection Method:clinical testing

The KMT2D c.11150A>G variant is predicted to result in the amino acid substitution p.Gln3717Arg. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.010% of alleles in individuals of Ashkenazi Jewish descent in gnomAD. At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
