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 was made for transcript

Our verdict: Likely_benign. The variant received -5 ACMG points.

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.

BP4

Computational evidence support a benign effect (MetaRNN=0.18017769).

BS2

High AC in GnomAdExome4 at 6 AD gene.
