(1) Disease for TMEM240 Gene


  • Spinocerebellar ataxia 21 (SCA21) [MIM:607454]: A form of spinocerebellar ataxia, 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. SCA21 is characterized by onset in the first decades of life of slowly progressive relatively mild cerebellar ataxia associated with slight extrapyramidal features predominant in older patients and cognitive impairment predominant in younger patients. Note=The disease is caused by mutations affecting the gene represented in this entry. {ECO:0000269 PubMed:25070513}.
