Genes affected

TARDBP (HGNC:11571): (TAR DNA binding protein) HIV-1, the causative agent of acquired immunodeficiency syndrome (AIDS), contains an RNA genome that produces a chromosomally integrated DNA during the replicative cycle. Activation of HIV-1 gene expression by the transactivator Tat is dependent on an RNA regulatory element (TAR) located downstream of the transcription initiation site. The protein encoded by this gene is a transcriptional repressor that binds to chromosomally integrated TAR DNA and represses HIV-1 transcription. In addition, this protein regulates alternate splicing of the CFTR gene. A similar pseudogene is present on chromosome 20. [provided by RefSeq, Jul 2008]

TARDBP links:

MASP2 (HGNC:6902): (MBL associated serine protease 2) This gene encodes a member of the peptidase S1 family of serine proteases. The encoded preproprotein is proteolytically processed to generate A and B chains that heterodimerize to form the mature protease. This protease cleaves complement components C2 and C4 in order to generate C3 convertase in the lectin pathway of the complement system. The encoded protease also plays a role in the coagulation cascade through cleavage of prothrombin to form thrombin. Myocardial infarction and acute stroke patients exhibit reduced serum concentrations of the encoded protein. Alternative splicing results in multiple transcript variants, at least one of which encodes an isoform that is proteolytically processed. [provided by RefSeq, Feb 2016]

This sequence change replaces methionine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 311 of the TARDBP protein (p.Met311Val). This variant is present in population databases (rs80356725, gnomAD 0.0009%). This missense change has been observed in individuals with amyotrophic lateral sclerosis (PMID: 19228676; Invitae). ClinVar contains an entry for this variant (Variation ID: 21487). 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 TARDBP protein function with a negative predictive value of 80%. Experimental studies have shown that this missense change affects TARDBP function (PMID: 28335005). In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic. -

The TARDBP c.931A>G variant is predicted to result in the amino acid substitution p.Met311Val. This variant was reported in an individual with amyotrophic lateral sclerosis (ALS, Lemmens et al. 2009. PubMed ID: 19228676). This variant is located within the conserved C-terminal region of TARDBP, where missense change is not expected to be tolerated and is considered a hot spot for ALS-causing variants (Tiloca et al. 2022. PubMed ID: 36247987). This variant is reported in 0.00088% of alleles in individuals of European (Non-Finnish) descent in gnomAD and has been interpreted as likely pathogenic in ClinVar. This variant is interpreted as likely pathogenic. -
