Genes affected

KMT5B (HGNC:24283): (lysine methyltransferase 5B) This gene encodes a protein that contains a SET domain. SET domains appear to be protein-protein interaction domains that mediate interactions with a family of proteins that display similarity with dual-specificity phosphatases (dsPTPases). The function of this gene has not been determined. Several alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2014]

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -2 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), KMT5B. . Gene score misZ 2.7894 (greater than the threshold 3.09). Trascript score misZ 3.742 (greater than threshold 3.09). GenCC has associacion of gene with complex neurodevelopmental disorder, intellectual disability, autosomal dominant 51.

BP4

Computational evidence support a benign effect (MetaRNN=0.4128685).

BS2

High AC in GnomAdExome4 at 5 AD gene.
