Genes affected
TLK2 (HGNC:11842): (tousled like kinase 2) This gene encodes a nuclear serine/threonine kinase that was first identified in Arabidopsis. The encoded protein is thought to function in the regulation of chromatin assembly in the S phase of the cell cycle by regulating the levels of a histone H3/H4 chaperone. This protein is associated with double-strand break repair of DNA damage caused by radiation. Pseudogenes of this gene are present on chromosomes 10 and 17. Alternate splicing results in multiple transcript variants. [provided by RefSeq, Sep 2013]

ACMG classification

Classification made for transcript

Verdict is Uncertain_significance. Variant got 4 ACMG points.

PM2
Very rare variant in population databases, with high coverage;
PP2
Missense variant in the TLK2 gene, where missense mutations are typically associated with disease (based on misZ statistic). The gene has 18 curated pathogenic missense variants (we use a threshold of 10). The gene has 4 curated benign missense variants. Gene score misZ: 4.4909 (above the threshold of 3.09). Trascript score misZ: 6.538 (above the threshold of 3.09). GenCC associations: The gene is linked to intellectual disability, autosomal dominant 57.
PP3
MetaRNN computational evidence supports a deleterious effect, 0.759
