Question
A 6-month-old baby cannot lift her head, can roll over, and has normal appetite. There are no significant abnormalities, but she sometimes trembles. What are the manifestations of children with chromosomal abnormalities?
Answer
Chromosomal abnormalities can be caused by various factors, including parental age and exposure to radiation during pregnancy. These abnormalities may lead to symptoms such as microcephaly, cleft lip and palate, and cavernous hemangiomas in children. Most children with chromosomal abnormalities die in infancy.
