Invitae RCV000546446 SCV000640619 uncertain significance Nemaline myopathy 2 2018-12-18 criteria provided, single submitter clinical testing This sequence change replaces histidine with arginine at codon 6144 of the NEB protein (p.His6144Arg). The histidine residue is weakly conserved and there is a small physicochemical difference between histidine and arginine. This variant is present in population databases (rs34504204, ExAC 0.09%). This variant has not been reported in the literature in individuals with NEB-related disease. ClinVar contains an entry for this variant (Variation ID: 331457). 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. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site, but this prediction has not been confirmed by published transcriptional studies. 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.
GeneDx RCV000606436 SCV000719636 likely benign not specified 2017-05-24 criteria provided, single submitter clinical testing This variant is considered likely benign or benign based on one or more of the following criteria: it is a conservative change, it occurs at a poorly conserved position in the protein, it is predicted to be benign by multiple in silico algorithms, and/or has population frequency not consistent with disease.
