Genes affected

KIF17 (HGNC:19167): (kinesin family member 17) Predicted to enable microtubule binding activity and plus-end-directed microtubule motor activity. Predicted to be involved in anterograde dendritic transport of neurotransmitter receptor complex and cell projection organization. Predicted to act upstream of or within microtubule-based process; protein-containing complex localization; and vesicle-mediated transport. Predicted to be located in microtubule cytoskeleton. Predicted to be part of intraciliary transport particle B and kinesin complex. Predicted to be active in cilium; microtubule cytoskeleton; and neuron projection.

The c.2683A>G (p.I895V) alteration is located in exon 12 (coding exon 12) of the KIF17 gene. This alteration results from a A to G substitution at nucleotide position 2683, causing the isoleucine (I) at amino acid position 895 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
