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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 22, 2022The c.2016G>A (p.M672I) alteration is located in exon 14 (coding exon 13) of the KIF18A gene. This alteration results from a G to A substitution at nucleotide position 2016, causing the methionine (M) at amino acid position 672 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
