Invitae | RCV000557849 | SCV000642302 | uncertain significance | Spinal muscular atrophy, distal, autosomal recessive, 1; Charcot-Marie-Tooth disease, axonal, type 2S | 2019-12-03 | criteria provided, single submitter | clinical testing | This sequence change replaces leucine with arginine at codon 426 of the IGHMBP2 protein (p.Leu426Arg). The leucine residue is moderately conserved and there is a moderate physicochemical difference between leucine and arginine. This variant is not present in population databases (ExAC no frequency). This variant has not been reported in the literature in individuals with an IGHMBP2-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: "Probably Damaging"; Align-GVGD: "Class C0"). In summary, this variant has uncertain impact on IGHMBP2 function. The available evidence is currently insufficient to determine its role in disease. Therefore, it has been classified as a Variant of Uncertain Significance. |
