Genes affected

KIF11 (HGNC:6388): (kinesin family member 11) This gene encodes a motor protein that belongs to the kinesin-like protein family. Members of this protein family are known to be involved in various kinds of spindle dynamics. The function of this gene product includes chromosome positioning, centrosome separation and establishing a bipolar spindle during cell mitosis. [provided by RefSeq, Jul 2008]

KIF11 Gene-Disease associations (from GenCC):

• ciliopathy

  Inheritance: AD Classification: DEFINITIVE Submitted by: Ambry Genetics
• microcephaly with or without chorioretinopathy, lymphedema, or intellectual disability
