Invitae | RCV000649541 | SCV000771370 | uncertain significance | Charcot-Marie-Tooth disease, axonal, type 2O | 2017-11-28 | criteria provided, single submitter | clinical testing | This sequence change replaces valine with isoleucine at codon 760 of the DYNC1H1 protein (p.Val760Ile). The valine residue is highly conserved and there is a small physicochemical difference between valine and isoleucine. This variant is present in population databases (rs781320162, ExAC 0.009%). This variant has not been reported in the literature in individuals with DYNC1H1-related disease. Algorithms developed to predict the effect of missense changes on protein structure and function do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C0"). 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. |
