Summaries for AFG3L2 Gene

Entrez Gene Summary for AFG3L2 Gene

  • This gene encodes a protein localized in mitochondria and closely related to paraplegin. The paraplegin gene is responsible for an autosomal recessive form of hereditary spastic paraplegia. This gene is a candidate gene for other hereditary spastic paraplegias or neurodegenerative disorders. [provided by RefSeq, Jul 2008]

Disorders for AFG3L2 Gene

(2) OMIM Diseases for AFG3L2 Gene (604581)


  • Spinocerebellar ataxia 28 (SCA28) [MIM:610246]: Spinocerebellar ataxia is a clinically and genetically heterogeneous group of cerebellar disorders. Patients show progressive incoordination of gait and often poor coordination of hands, speech and eye movements, due to degeneration of the cerebellum with variable involvement of the brainstem and spinal cord. SCA28 is an autosomal dominant cerebellar ataxia (ADCA) with a slow progressive course and no evidence of sensory involvement or cognitive impairment. {ECO:0000269 PubMed:20208537, ECO:0000269 PubMed:20354562, ECO:0000269 PubMed:20725928}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Spastic ataxia 5, autosomal recessive (SPAX5) [MIM:614487]: A neurodegenerative disorder characterized by early onset spasticity, peripheral neuropathy, ptosis, oculomotor apraxia, dystonia, cerebellar atrophy, and progressive myoclonic epilepsy. {ECO:0000269 PubMed:22022284}. Note=The disease is caused by mutations affecting the gene represented in this entry.
