Invitae RCV000560472 SCV000651638 uncertain significance Charcot-Marie-Tooth disease axonal type 2O 2023-08-17 criteria provided, single submitter clinical testing 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: 472529). This variant has not been reported in the literature in individuals affected with DYNC1H1-related conditions. The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. This sequence change replaces aspartic acid, which is acidic and polar, with asparagine, which is neutral and polar, at codon 1256 of the DYNC1H1 protein (p.Asp1256Asn).
PreventionGenetics, part of Exact Sciences RCV003900220 SCV004715808 uncertain significance DYNC1H1-related condition 2024-01-25 criteria provided, single submitter clinical testing The DYNC1H1 c.3766G>A variant is predicted to result in the amino acid substitution p.Asp1256Asn. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.0040% of alleles in individuals of African descent in gnomAD. At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence.
