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]

Classification made for transcript

Verdict is Uncertain_significance. Variant got 0 ACMG points.

PM1

In a zinc_finger_region PHD-type 7 (size 47) in uniprot entity KMT2D_HUMAN there are 7 pathogenic changes around while only 2 benign (78%) in NM_003482.4

PM2

Very rare variant in population databases, with high coverage;

PP2

Missense variant in gene, where missense usually causes diseases (based on misZ statistic), KMT2D. . Gene score misZ 3.7288 (greater than the threshold 3.09). Trascript score misZ 4.6964 (greater than threshold 3.09). GenCC has associacion of gene with Kabuki syndrome, branchial arch abnormalities, choanal atresia, athelia, hearing loss, and hypothyroidism syndrome, Kabuki syndrome 1, choanal atresia-athelia-hypothyroidism-delayed puberty-short stature syndrome.

PP3

MetaRNN computational evidence supports a deleterious effect, 0.784

BP6
