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]

The variant is observed at an extremely low frequency in the gnomAD v4.0.0 dataset (total allele frequency: <0.001%). Predicted Consequence/Location: Missense changes are a common disease-causing mechanism. Functional studies provide moderate evidence of the variant having a damaging effect on the gene or gene product (PMID: 25090004, 29630989). The same nucleotide change resulting in the same amino acid change has been previously reported as pathogenic/likely pathogenic with strong evidence (ClinVar ID: VCV000021484 /PMID: 19224587). The variant has been observed in at least two similarly affected unrelated individuals (PMID: 19864664, 21651514). A different missense change at the same codon (p.Gly294Ala) has been reported to be associated with TARDBP related disorder (ClinVar ID: VCV000005230 /PMID: 18309045). Therefore, this variant is classified as Pathogenic according to the recommendation of ACMG/AMP guideline.

The frequency of this variant in the general population is consistent with pathogenicity (Genome Aggregation Database [gnomAD], Cambridge, MA [URL: http://gnomad.broadinstitute.org]). Reports of this variant in asymptomatic individuals well past typical age of onset suggest this variant exhibits reduced penetrance (PMID: 19224587, 22722621, 31852254). This variant is statistically more frequent in affected individuals than in the general population and/or healthy controls. Experiments in patient-derived cell lines showed aberrant stress granule formation and disassembly, as well as severely impaired organelle transport along neuronal axons (PMID: 27570075, 29630989).

The TARDBP c.881G>T variant is predicted to result in the amino acid substitution p.Gly294Val. This variant has been reported in multiple, unrelated individuals with amyotrophic lateral sclerosis (ALS) based on the literature and in our internal data (Corrado et al. 2009. PubMed ID: 19224587; Bartoletti-Stella et al. 2018. PubMed ID: 29525180; Wang et al. 2020. PubMed ID: 33159016). A different missense variant (c.881G>C, p.Gly294Ala) has also been reported to be causative of ALS (Sreedharan et al. 2008. PubMed ID: 18309045). This variant is located within the well-characterized gene hotspot known to harbor pathogenic variation. This variant is reported in 0.0026% of alleles in individuals of European (Non-Finnish) descent in gnomAD; and has been consistently classified as pathogenic in ClinVar (https://www.ncbi.nlm.nih.gov/clinvar/variation/21484/). This variant is interpreted as pathogenic.

This sequence change replaces glycine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 294 of the TARDBP protein (p.Gly294Val). This variant is present in population databases (rs80356721, gnomAD 0.004%), including at least one homozygous and/or hemizygous individual. This missense change has been observed in individuals with amyotrophic lateral sclerosis (PMID: 19864664, 21651514, 29630989). ClinVar contains an entry for this variant (Variation ID: 21484). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) 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: 25090004). For these reasons, this variant has been classified as Pathogenic.
