Invitae | RCV000794750 | SCV000934177 | uncertain significance | Spinal muscular atrophy, distal, autosomal recessive, 1; Charcot-Marie-Tooth disease, axonal, type 2S | 2018-11-14 | criteria provided, single submitter | clinical testing | This sequence change replaces threonine with methionine at codon 484 of the IGHMBP2 protein (p.Thr484Met). The threonine residue is highly conserved and there is a moderate physicochemical difference between threonine and methionine. This variant is not present in population databases (ExAC no frequency). This variant has been observed in an individual affected with Charcot-Marie-Tooth disease (CMT) (PMID: 26392352). Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Tolerated"; 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. |
