Genes affected
KIF2C (HGNC:6393): (kinesin family member 2C) This gene encodes a kinesin-like protein that functions as a microtubule-dependent molecular motor. The encoded protein can depolymerize microtubules at the plus end, thereby promoting mitotic chromosome segregation. Alternative splicing results in multiple transcript variants.

Submissions by phenotype
not specified Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Dec 21, 2022 | The c.341T>C (p.M114T) alteration is located in exon 5 (coding exon 5) of the KIF2C gene. This alteration results from a T to C substitution at nucleotide position 341, causing the methionine (M) at amino acid position 114 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |
