Genes affected

KIF27 (HGNC:18632): (kinesin family member 27) This gene is a member of the KIF27 (kinesin 4) sub-family of the mammalian kinesin family. The gene is an ortholog of the Drosophila Cos2 gene, which plays an important role in the Hedgehog signaling pathway. The encoded protein contains an N-terminal motor domain which includes nucleotide-binding and microtubule-interacting regions, a stalk domain containing a predicted coiled coil motif and a C-terminal tail domain. Alternatively spliced transcript variants have been observed for this gene. Pseudogenes associated with this gene are located on chromosome 9. [provided by RefSeq, Dec 2012]

The c.4079G>A (p.R1360Q) alteration is located in exon 18 (coding exon 17) of the KIF27 gene. This alteration results from a G to A substitution at nucleotide position 4079, causing the arginine (R) at amino acid position 1360 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
