Genes affected
KIZ (HGNC:15865): (kizuna centrosomal protein) The protein encoded by this gene localizes to centrosomes, strengthening and stabilizing the pericentriolar region prior to spindle formation. The encoded protein usually remains with the mother centrosome after centrosomal duplication. Sevral transcript variants encoding different isoforms have been found for this gene.

Submissions by phenotype
not specified Uncertain:1
| Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Dec 11, 2023 | The c.466G>C (p.A156P) alteration is located in exon 5 (coding exon 5) of the KIZ gene. This alteration results from a G to C substitution at nucleotide position 466, causing the alanine (A) at amino acid position 156 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |
not provided Uncertain:1
| Uncertain significance, criteria provided, single submitter | clinical testing | Labcorp Genetics (formerly Invitae), Labcorp | Jul 22, 2024 | This sequence change replaces alanine, which is neutral and non-polar, with proline, which is neutral and non-polar, at codon 156 of the KIZ protein (p.Ala156Pro). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with KIZ-related conditions. ClinVar contains an entry for this variant (Variation ID: 2116928). 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. - |
