Genes affected

KIF12 (HGNC:21495): (kinesin family member 12) This gene encodes a member of the kinesin superfamily of microtubule-associated molecular motors with functions related to the microtubule cytosekelton. Members of this superfamily play important roles in intracellular transport and cell division. A similar protein in mouse functions in the beta cell antioxidant signaling cascade, acting as a scaffold for the transcription factor specificity protein 1 (Sp1). Mice that lack this gene exhibit beta cell oxidative stress resulting in hypoinsulinemic glucose intolerance. [provided by RefSeq, Jul 2016]

This sequence change replaces glycine, which is neutral and non-polar, with arginine, which is basic and polar, at codon 471 of the KIF12 protein (p.Gly471Arg). 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. 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: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0"). This variant has not been reported in the literature in individuals affected with KIF12-related conditions. This variant is present in population databases (rs370618777, gnomAD 0.04%). -
