Patient's question:
On June 1, 2005, test and examination results: Chromosomes are fine.Past treatment history and effectiveness: None.
What kind of help you want: I want to have another child to see if it is hereditary.
Doctor's answer:
21 trisomy syndrome, also known as congenital idiocy syndrome, is a type of chromosomal abnormality. It is the most common chromosomal disease in children. The incidence of liveborn 21 trisomy is approximately 1/600-1000. The older the mother, the higher the incidence of this disease. Guidelines: The recurrence risk for standard 21 trisomy syndrome is 1%. The older the mother, the higher the risk. Women with fertility who have this disease have a 50% incidence of the disease in their offspring; in translocation type, the recurrence risk is 4%-10%, but if the mother carries a 21q22q translocation, then 100% of the next generation will have the disease. High-risk pregnant women can undergo a series of prenatal tests, which are helpful for diagnosis.
