RCV000544120 | SCV000644835 | uncertain significance | Amyotrophic lateral sclerosis type 1; Perry syndrome; Neuronopathy, distal hereditary motor, type 7B | 2017-04-03 | criteria provided, single submitter | clinical testing | This sequence change replaces glutamic acid with valine at codon 278 of the DCTN1 protein (p.Glu278Val). The glutamic acid residue is highly conserved and there is a moderate physicochemical difference between glutamic acid and valine. This variant is not present in population databases (ExAC no frequency) and has not been reported in the literature in individuals with a DCTN1-related disease. 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 disruptive, but these predictions have not been confirmed by published functional studies. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may alter RNA splicing, but this prediction has not been confirmed by published transcriptional studies. In summary, this variant is a novel missense change with uncertain impact on protein function. It has been classified as a Variant of Uncertain Significance. |
