If you have a child found to have limb-girdle muscular dystrophy type 2, there is a 25% (1 in 4) chance with every pregnancy to have another child with the same condition (assuming both parents are the same). If your child has a genetic diagnosis, you can test future pregnancies or children at birth for the condition. Since this condition is inherited, you and your partner should also have testing for the same mutations found in your child. People who have one mutation in one copy of the associated gene are called carriers of LGMD2. This means that they carry one mutation but do not show symptoms of the condition. You and your partner’s siblings, parents, and other relatives can consider testing for the same genetic mutations, and genetic counseling to learn more about their individual risks.
If you are concerned about the risk of having a child with LGMD and the options available, you may wish to speak to a certified genetic counselor, who can answer your questions and tailor the information to your specific situation. A list of genetic counselors is available on the National Society of Genetic Counselors website as well as on the Canadian Association of Genetic Counsellors website.
