- Huntington's disease (HD): People with a family history of Huntington's disease, should consider genetic counselling before starting a family. Genetic testing done by blood sampling can help to identify the faulty gene, even before the signs or symptoms show. The risk of a child being affected with HD is 50% if one parent carries the defective gene. If you have the genetic defect that causes Huntington's disease, consider adoption or certain forms of assisted reproduction.
- Sydenham’s chorea: Penicillin prophylaxis over the course of the next 10 years is recommended to prevent additional manifestations of rheumatic fever and the recurrence of Sydenham’s chorea. Women with Sydenham’s chorea have the risk of recurrence on exposure to oral contraceptives and pregnancy. However, both these conditions are considered preventable states. Certain drugs such as digoxin and phenytoin also increase the risk of the recurrence of Sydenham’s chorea.
