When a mother goes to the hospital for examination and Down syndrome screening, if there is a high risk of trisomy 18, parents must take it seriously because trisomy 18 syndrome is one of the important causes of fetal death during the perinatal period. So, trisomy 18 high risk refers to where the baby's body shows bad signals?
Chromosomes are a type of genetic material and a carrier of genes. Normally, any chromosome in the human body is diploid, and triploidy is an abnormal phenomenon that may have certain abnormal effects on various parts of the body. The 18th chromosome is related to human intelligence, and triploidy of the fetus's 18th chromosome may have an impact on the child's intelligence. In addition to congenital malformations, survivors also exhibit significant intellectual disability and poor prognosis, making prenatal diagnosis very important.
The high-risk cause of trisomy 18 is the non segregation of chromosome 18 during cell division, which is often associated with advanced maternal age and aging of egg cells, but is also related to other factors such as physical, chemical, genetic, and so on. The high-risk situation of trisomy 18 will also be screened during routine pregnancy tests, so pregnant women should actively cooperate with pregnancy tests. It is recommended to undergo amniocentesis for early diagnosis. If trisomy 18 is diagnosed, it is a congenital genetic disease that can affect the intellectual development of the fetus. Termination of pregnancy may be considered.
