Genes affected

KIF25 (HGNC:6390): (kinesin family member 25) The protein encoded by this gene is a member of the kinesin-like protein family. Protein family members are microtubule-dependent molecular motors that transport organelles within cells and move chromosomes during cell division. However, the particular function of this gene product has not yet been determined. Two alternatively spliced transcript variants which encode products have been described. Other splice variants have been found that lack exon 2 and the initiation codon for translation. [provided by RefSeq, Jul 2008]

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.260C>T (p.P87L) alteration is located in exon 4 (coding exon 3) of the KIF25 gene. This alteration results from a C to T substitution at nucleotide position 260, causing the proline (P) at amino acid position 87 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
