Genes affected

KIF18A (HGNC:29441): (kinesin family member 18A) KIF18A is a member of the kinesin superfamily of microtubule-associated molecular motors (see MIM 148760) that use hydrolysis of ATP to produce force and movement along microtubules (Luboshits and Benayahu, 2005 [PubMed 15878648]).[supplied by OMIM, Aug 2008]

The c.2539A>C (p.N847H) alteration is located in exon 16 (coding exon 15) of the KIF18A gene. This alteration results from a A to C substitution at nucleotide position 2539, causing the asparagine (N) at amino acid position 847 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
