Invitae RCV000529524 SCV000651633 uncertain significance Charcot-Marie-Tooth disease, axonal, type 2O 2018-06-13 criteria provided, single submitter clinical testing This sequence change replaces histidine with arginine at codon 891 of the DYNC1H1 protein (p.His891Arg). The histidine residue is moderately conserved and there is a small physicochemical difference between histidine and arginine. This variant is present in population databases (rs774004189, ExAC 0.01%). This variant has not been reported in the literature in individuals with a DYNC1H1-related disease. ClinVar contains an entry for this variant (Variation ID: 312624). Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated, but these predictions have not been confirmed by published functional studies and their clinical significance is uncertain. In summary, this variant has uncertain impact on DYNC1H1 function. The available evidence is currently insufficient to determine its role in disease. Therefore, it has been classified as a Variant of Uncertain Significance.
