RCV000698045 | SCV000826686 | pathogenic | TWIST1-related craniosynostosis; Saethre-Chotzen syndrome | 2024-06-26 | criteria provided, single submitter | clinical testing | This sequence change creates a premature translational stop signal (p.Gln101*) in the TWIST1 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in TWIST1 are known to be pathogenic (PMID: 10749989). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with TWIST1-related conditions. ClinVar contains an entry for this variant (Variation ID: 575739). For these reasons, this variant has been classified as Pathogenic. |

RCV000760816 | SCV000890711 | likely pathogenic | not provided | 2018-10-17 | criteria provided, single submitter | clinical testing | The Q101X variant in the TWIST1 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 through protein truncation, as the last 102 amino acids are lost. The Q101X variant is not observed in large population cohorts (Lek et al., 2016). We interpret Q101X as a likely pathogenic variant. |
