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]

The TBK1 c.149A>C variant is predicted to result in the amino acid substitution p.Asp50Ala. This variant has not been reported in individuals with neurodegenerative disease in the literature. This variant is reported in 0.00091% of alleles in individuals of European (Non-Finnish) descent in gnomAD. At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -

In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site. Experimental studies have shown that this missense change affects TBK1 function (PMID: 22851595, 28008748). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt TBK1 protein function. ClinVar contains an entry for this variant (Variation ID: 495316). This missense change has been observed in individual(s) with herpes simplex encephalitis (PMID: 22851595). This variant is present in population databases (no rsID available, gnomAD 0.0009%). This sequence change replaces aspartic acid, which is acidic and polar, with alanine, which is neutral and non-polar, at codon 50 of the TBK1 protein (p.Asp50Ala). -
