Hi, Translocation aberration in chromosomes can be inherited from one or both parents, or it can occur spontaneously during the development of an embryo. In the case of a balanced translocation, where no genetic material is lost or gained, the person carrying the translocation may have no symptoms or health problems. However, if the translocation is unbalanced, meaning there is a loss or gain of genetic material, it can lead to developmental abnormalities or health issues. In terms of future pregnancies, if you or your partner carry a balanced translocation, there is a risk that it could be passed on to your offspring. This can result in an unbalanced translocation, which can cause miscarriage or birth defects. Genetic counseling can help determine your risk and make informed decisions about your future pregnancies. If your missed abortion was due to numerical abnormality and translocation aberration in chromosomes, it is possible that it could happen again in future pregnancies. However, the risk will depend on the specific nature of the translocation and other factors such as your age and overall health. It is important to discuss your concerns with your healthcare provider and a genetic counselor to understand your specific risk and options for future pregnancies. Take care.
