| 617770 | OMIM | Spinocerebellar ataxia 46 (SCA46) | 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. SCA46 is a slowly progressive, autosomal dominant form with onset in adulthood. The disease may be caused by variants affecting the gene represented in this entry. There is limited evidences for implication of PLD3 in SCA46. Knockout mice do not present signs of cerebellar degeneration or spinocerebellar ataxia at 9 months of age, challenging the interpretation of the suggested loss-of-function mechanism for PLD3 as the SCA46-causative gene. |
