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]

Ambry Genetics

Jul 14, 2023

The c.1326G>A (p.M442I) alteration is located in exon 15 (coding exon 13) of the KIF12 gene. This alteration results from a G to A substitution at nucleotide position 1326, causing the methionine (M) at amino acid position 442 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
