On this page, you will find information about a genetic change that was identified in a UDN participant. We are trying to find others with the same or similar condition.

 Sharing information on this website is not a requirement of UDN participation. Only descriptions about participants who give explicit consent will appear here.

A change in the CCNF gene was identified in a female, age 9, with brain abnormalities (abnormal cerebellum morphology, cerebellar atrophy), stiffness of the legs (spastic paraplegia) and muscle fiber disease (myopathy) (read full description).

Date of Report

Full Name

cyclin F

Chromosome 16 (16p13.3)


Cyclin F is the largest known human cyclin and is one of the components of a SCF (SKP1-CUL1-F-box protein) E3 ubiquitin-protein ligase complex. This complex mediates the ubiquitination and degradation of CP110, which is essential in mitosis and required for genome integrity (D’Angiolella et al., 2010).
