Genes affected
KIF22 (HGNC:6391): (kinesin family member 22) The protein encoded by this gene is a member of the kinesin-like protein family. The family members are microtubule-dependent molecular motors that transport organelles within cells and move chromosomes during cell division. The C-terminal half of this protein has been shown to bind DNA. Studies with the Xenopus homolog suggests its essential role in metaphase chromosome alignment and maintenance. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jan 2012]

Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpNov 04, 2023This variant, c.51_62del, results in the deletion of 4 amino acid(s) of the KIF22 protein (p.Ser18_Ala21del), but otherwise preserves the integrity of the reading frame. This variant is present in population databases (rs762787353, gnomAD 0.06%), including at least one homozygous and/or hemizygous individual. This variant has not been reported in the literature in individuals affected with KIF22-related conditions. ClinVar contains an entry for this variant (Variation ID: 2139719). Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
