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.2309C>T (p.P770L) alteration is located in exon 21 (coding exon 21) of the KIF6 gene. This alteration results from a C to T substitution at nucleotide position 2309, causing the proline (P) at amino acid position 770 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
