RCV000599095 | SCV000710469 | uncertain significance | not provided | 2018-01-31 | criteria provided, single submitter | clinical testing | The R287X variant in the TBXAS1 gene has not been reported previously as a pathogenic variant nor as a benign variant, to our knowledge. This variant is predicted to cause loss of normal protein function either through protein truncation or nonsense-mediated mRNA decay. The R287X variant is observed in 7/18866 (0.04%) alleles from individuals of East Asian background, and in 20/275,228 total alleles in large population cohorts (Lek et al., 2016). We interpret R287X as a variant of uncertain significance. |

RCV000599095 | SCV003786643 | pathogenic | not provided | 2023-11-10 | criteria provided, single submitter | clinical testing | This sequence change creates a premature translational stop signal (p.Arg287*) in the TBXAS1 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in TBXAS1 are known to be pathogenic (PMID: 22735388). This variant is present in population databases (rs766799764, gnomAD 0.04%). This variant has not been reported in the literature in individuals affected with TBXAS1-related conditions. ClinVar contains an entry for this variant (Variation ID: 504161). For these reasons, this variant has been classified as Pathogenic. |
