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]

Review Status: criteria provided, single submitter
Collection Method: clinical testing

The c.1500T>G (p.S500R) alteration is located in exon 16 (coding exon 14) of the KIF12 gene. This alteration results from a T to G substitution at nucleotide position 1500, causing the serine (S) at amino acid position 500 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
