Genes affected

KIF6 (HGNC:21202): (kinesin family member 6) This gene encodes a member of a family of molecular motors which are involved in intracellular transport of protein complexes, membrane organelles, and messenger ribonucleic acid along microtubules. Kinesins function as homodimeric molecules with two N-terminal head domains that move along microtubules and two C-terminal tail domains that interact with the transported cargo, either directly or indirectly, through adapter molecules. This gene is ubiquitously expressed in coronary arteries and other vascular tissue. A naturally occurring mutation in this gene is associated with coronary heart disease.

The c.1501C>G (p.R501G) alteration is located in exon 13 (coding exon 13) of the KIF6 gene. This alteration results from a C to G substitution at nucleotide position 1501, causing the arginine (R) at amino acid position 501 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
