| Invitae | RCV001066710 | SCV001231727 | uncertain significance | Charcot-Marie-Tooth disease axonal type 2O | 2023-05-15 | criteria provided, single submitter | clinical testing | This variant has not been reported in the literature in individuals affected with DYNC1H1-related conditions. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. 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) has been performed at Invitae for this missense variant, however the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on DYNC1H1 protein function. ClinVar contains an entry for this variant (Variation ID: 860418). This variant is not present in population databases (gnomAD no frequency). This sequence change replaces alanine, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 2651 of the DYNC1H1 protein (p.Ala2651Thr). |

RCV003396711 | SCV004111411 | uncertain significance | DYNC1H1-related condition | 2023-05-25 | criteria provided, single submitter | clinical testing | The DYNC1H1 c.7951G>A variant is predicted to result in the amino acid substitution p.Ala2651Thr. To our knowledge, this variant has not been reported in the literature or in a large population database (http://gnomad.broadinstitute.org), indicating this variant is rare. At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. |
