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 Benign. Variant got -8 ACMG points.

BS1
Variant frequency is greater than expected in population sas. gnomad4 allele frequency = 0.000312 (47/150616) while in subpopulation SAS AF= 0.00146 (7/4798). AF 95% confidence interval is 0.000684. There are 0 homozygotes in gnomad4. There are 23 alleles in male gnomad4 subpopulation. Median coverage is 31. This position pass quality control queck.
BS2
High AC in GnomAd4 at 47 AD gene.
