Patient's question:
When undergoing pre-pregnancy testing, I noticed that there is a chromosomal test included. I don't quite understand this test, so I'd like to ask: if there is a chromosomal abnormality, what are the characteristics of chromosomal disorders?Doctor's answer:
Chromosomes are divided into autosomal and sex chromosome diseases. The most prominent feature of chromosomal diseases is their hereditary nature, so it is very important to have a thorough chromosomal examination at the hospital before pregnancy. Chromosomal diseases can cause patients to experience delayed growth and development, intellectual developmental delays, and congenital deformities. For example, Down syndrome is a very common chromosomal disease, and so far, there is still no effective treatment available.
