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]

Pathogenic, no assertion criteria provided | literature only | OMIM | Apr 29, 2022 | - - |
Uncertain significance, criteria provided, single submitter | curation | SIB Swiss Institute of Bioinformatics | Oct 15, 2018 | This variant is interpreted as Uncertain Significance - Insufficient Evidence, for Mental retardation, autosomal dominant 57. The following ACMG Tag(s) were applied: PM2 => Absent from controls (or at extremely low frequency if recessive) in Exome Sequencing Project, 1000 Genomes Project, or Exome Aggregation Consortium. PP3 => Multiple lines of computational evidence support a deleterious effect on the gene or gene product. PM6 => Assumed de novo, but without confirmation of paternity and maternity (https://www.ncbi.nlm.nih.gov/pubmed/29861108). - |
