Causes of Kartagener syndrome. Kartagener syndrome is caused by a mutation in the DNAI1 gene, which makes a cellular protein required for normal functioning cilia (cilia line the respiratory tract) and sperm motility.
PINK1 appears to be a rare cause of inherited Parkinson's disease. A small percentage (~2 percent) of those developing the condition at an early age appear to carry mutations in the PINK1 gene. Genetic testing for the PARK7, SNCA and LRRK2 genes is also available. Individuals and families who are interested in having genetic testing can learn more about their risk for Parkinson's disease and the availability and accuracy of genetic testing for this disease by setting up an appointment with a genetics health professional.
