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]

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -1 ACMG points.

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.

BP4

Computational evidence support a benign effect (MetaRNN=0.121735096).
