Invitae | RCV000560786 | SCV000640709 | uncertain significance | Nemaline myopathy 2 | 2017-06-21 | criteria provided, single submitter | clinical testing | This sequence change replaces histidine with arginine at codon 7506 of the NEB protein (p.His7506Arg). The histidine residue is moderately conserved and there is a small physicochemical difference between histidine and arginine. This variant is not present in population databases (ExAC no frequency) and has not been reported in the literature in individuals with a NEB-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 tolerated, but these predictions have not been confirmed by published functional studies. In summary, this variant is a novel missense change that is not predicted to affect protein function. There is no indication that it causes disease, but the available evidence is currently insufficient to prove that conclusively. Therefore, it has been classified as a Variant of Uncertain Significance. |
