Invitae RCV000536275 SCV000640547 uncertain significance Nemaline myopathy 2 2016-05-30 criteria provided, single submitter clinical testing This sequence change replaces glutamine with arginine at codon 4351 of the NEB protein (p.Gln4351Arg). The glutamine residue is weakly conserved and there is a small physicochemical difference between glutamine and arginine. This variant occurs in a region of NEB (Exons 82-105) consisting of three highly homologous 8-exon repeat units (exons 82-89, exons 90-97, exons 98-105). Sequence variants in this region can be detected, but this assay cannot determine which of the three repeat units is affected, and zygosity is often ambiguous. All variants in this region are reported relative to the exon 82-89 repeat. 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. In summary, this variant is a novel missense change that is not predicted to affect protein function. Missense variants in the NEB gene are typically not pathogenic, and there is no indication that this variant causes disease. However, the available evidence is currently insufficient to prove that conclusively. Therefore, it has been classified as a Variant of Uncertain Significance.
