Genes affected

KIF26B (HGNC:25484): (kinesin family member 26B) The protein encoded by this gene is an intracellular motor protein thought to transport organelles along microtubules. The encoded protein is required for kidney development. Elevated levels of this protein have been found in some breast and colorectal cancers. [provided by RefSeq, Mar 2017]

LOC105373265 (HGNC:):
