The lysine residue is highly conserved and there is a small physicochemical difference between lysine and arginine. This sequence change has been reported in a patient affected with CMT2 (PMID: 25025039) and is present in population databases (rs373698346, 0.01%). 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"; MutationTaster: "disease-causing"; Align-GVGD: "Class C0"). In summary, this is a rare missense change that has been observed in a CMT2 patient with uncertain impact on protein function. Therefore, it has been classified as a Variant of Uncertain Significance.
