Genes affected

KLC2 (HGNC:20716): (kinesin light chain 2) The protein encoded by this gene is a light chain of kinesin, a molecular motor responsible for moving vesicles and organelles along microtubules. Defects in this gene are a cause of spastic paraplegia, optic atrophy, and neuropathy (SPOAN) syndrome. [provided by RefSeq, Mar 2016]

KLC2 Gene-Disease associations (from GenCC):

• spastic paraplegia, optic atropy, and neuropathy

  Inheritance: AR Classification: SUPPORTIVE, LIMITED Submitted by: Ambry Genetics, Orphanet, Labcorp Genetics (formerly Invitae)
