Question
A 6-month-old baby cannot lift their head, can roll over, and has normal appetite. There are no significant abnormalities, but the baby sometimes trembles. What are chromosomal abnormalities?
Answer
Chromosomal abnormalities are mainly caused by incomplete chromosome development, leading to a series of genetic diseases. Children may experience many intellectual disabilities and growth delays. Conditions like Trisomy 21 or Down syndrome, one of the most common chromosomal abnormality diseases in humans, can lead to intellectual development disorders and many mental developmental delays. Timely treatment for the child can help with their growth and development. If the chromosomal abnormality is severe, it may lead to further deformities in various aspects of the child.
