How long a child can live with a genetic mutation is determined by the disease caused by the mutation, the complications, and the aftercare. Genetic mutations in children may cause related diseases, such as the development of albinism or other genetic diseases, which may affect health. For diseases caused by genetic mutations in children, the main focus is on symptomatic treatment based on the lesions caused by the disease to improve the child’s clinical symptoms and enhance the child’s quality of life and ability to care for him/herself, but there is no particularly effective gene therapy method yet. If a child with a gene mutation is properly cared for and no complications occur, he or she can be kept alive for a certain period of time, for which there are no clinical statistics. If serious complications occur, they may be life-threatening. Children diagnosed with genetic mutations are recommended to go to the genetics department of the hospital for consultation or to the rehabilitation department for evaluation and physical, skill and intellectual training.
