Invitae | RCV000642636 | SCV000764323 | uncertain significance | Spinal muscular atrophy, distal, autosomal recessive, 1; Charcot-Marie-Tooth disease, axonal, type 2S | 2017-12-27 | criteria provided, single submitter | clinical testing | This sequence change replaces aspartic acid with asparagine at codon 400 of the IGHMBP2 protein (p.Asp400Asn). The aspartic acid residue is highly conserved and there is a small physicochemical difference between aspartic acid and asparagine. This variant is present in population databases (rs779654686, ExAC 0.002%). This variant has not been reported in the literature in individuals with 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, 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. |
