Invitae | RCV000556624 | SCV000644069 | uncertain significance | Charcot-Marie-Tooth disease, type 4A | 2017-04-04 | criteria provided, single submitter | clinical testing | This sequence change replaces proline with threonine at codon 144 of the GDAP1 protein (p.Pro144Thr). The proline residue is highly conserved and there is a small physicochemical difference between proline and threonine. This variant is not present in population databases (ExAC no frequency) and has not been reported in the literature in individuals with a GDAP1-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: "Tolerated"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). In summary, this variant is a novel missense change with uncertain impact on protein function. It has been classified as a Variant of Uncertain Significance. |
