There is currently no more effective treatment for Down syndrome, so it is best to undergo relevant prenatal examinations during pregnancy. If this disease is detected, the pregnancy should be terminated early. Reasonable prenatal diagnosis is a very effective measure to prevent the birth of Down syndrome babies. So what are the three levels of Down syndrome? Let's all learn about it together!
Down syndrome is mainly classified into three levels based on the type of disease: standard type, translocation type, and chimeric type. The standard type accounts for about 95% of Down syndrome, which refers to the number of chromosomes in the child's body being 47, with an additional chromosome 21.
The number of chromosomes in children with translocation type is 46, and a few children show chromosome 15 translocation. This translocation symptom is accompanied by a certain degree of heritability, mostly due to carriers of translocation chromosomes in close relatives. And the embedded body type is mostly due to an increase in 21 trisomy cells, and the higher the proportion, the more intellectually backward the babies born in the future will be.
Furthermore, after the birth of Down syndrome babies, they often exhibit poor emotional regulation ability and significant fluctuations, requiring long-term education and training for the affected children. If this disease is found during the examination, reasonable measures must be taken to minimize the birth of Down syndrome babies. The older the age, the higher the probability of this disease occurring, so it is necessary for elderly mothers to undergo this examination.
