Question: Is Olivopontocerebellar atrophy inherited ?
Answer: Is olivopontocerebellar atrophy inherited? Olivopontocerebellar atrophy (OPCA) may be associated with conditions that are inherited (genetic), or it may occur sporadically. Genetic forms of OPCA may be inherited in an autosomal dominant, autosomal recessive, or X-linked manner. The inheritance pattern depends on the specific genetic cause. For example, OPCA associated with spinocerebellar ataxia 3 is inherited in an autosomal dominant manner. Most types of inherited OPCA are associated with spinocerebellar ataxias that follow autosomal dominant inheritance. Sporadic OPCA refers to when the condition occurs for unknown reasons, or when there is no evidence of a genetic basis. Some people with sporadic OPCA will eventually develop multiple system atrophy (MSA). People with a personal or family history of OPCA are encouraged to speak with a genetic counselor or other genetics professional. A genetics professional can evaluate the family history; address questions and concerns; assess recurrence risks; and facilitate genetic testing if desired.
