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.1897G>A (p.D633N) alteration is located in exon 17 (coding exon 17) of the KIF6 gene. This alteration results from a G to A substitution at nucleotide position 1897, causing the aspartic acid (D) at amino acid position 633 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
