From NCBI Gene:
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]
Kinesin is a microtubule-associated force-producing protein that may play a role in organelle transport. The light chain may function in coupling of cargo to the heavy chain or in the modulation of its ATPase activity.

- Spastic paraplegia, optic atrophy, and neuropathy
Spastic paraplegia, optic atrophy, and neuropathy (SPOAN): A form of spastic paraplegia, a neurodegenerative disorder characterized by a slow, gradual, progressive weakness and spasticity of the lower limbs. Rate of progression and the severity of symptoms are quite variable. Initial symptoms may include difficulty with balance, weakness and stiffness in the legs, muscle spasms, and dragging the toes when walking. In some forms of the disorder, bladder symptoms (such as incontinence) may appear, or the weakness and stiffness may spread to other parts of the body. SPOAN is characterized by spastic paraplegia with progressive joint contractures and spine deformities, loss of independent ambulation by age 10 years, sub-normal vision secondary to congenital optic atrophy, and neuropathy. Inheritance is autosomal recessive. [MIM:609541]
