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.73C>T variant is predicted to result in the amino acid substitution p.Arg25Cys. To our knowledge, this variant has not been reported in the literature; however, another single nucleotide variant impacting the same amino acid (c.74G>A, p.Arg25His) has been reported in individual(s) with amyotrophic lateral sclerosis (Cirulli ET et al. 2015. PubMed ID: 25700176). This variant is reported in 0.0033% of alleles in individuals of South Asian descent in gnomAD (http://gnomad.broadinstitute.org/variant/12-64849723-C-T). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
