Genes affected

TBK1 (HGNC:11584): (TANK binding kinase 1) The NF-kappa-B (NFKB) complex of proteins is inhibited by I-kappa-B (IKB) proteins, which inactivate NFKB by trapping it in the cytoplasm. Phosphorylation of serine residues on the IKB proteins by IKB kinases marks them for destruction via the ubiquitination pathway, thereby allowing activation and nuclear translocation of the NFKB complex. The protein encoded by this gene is similar to IKB kinases and can mediate NFKB activation in response to certain growth factors. The protein is also an important kinase for antiviral innate immunity response. [provided by RefSeq, Sep 2021]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -13 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.019347101).

BP6

Variant 12-64481993-C-T is Benign according to our data. Variant chr12-64481993-C-T is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 252679.

BS1

Variant frequency is greater than expected in population sas. GnomAd4 allele frequency = 0.000348 (53/152206) while in subpopulation SAS AF = 0.00145 (7/4820). AF 95% confidence interval is 0.000681. There are 0 homozygotes in GnomAd4. There are 25 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.

BS2

High Homozygotes in GnomAdExome4 at 2 AD,AR gene
