prenatal chromosomal abnormalities

Prenatal chromosomal abnormalities occur when there are changes or mistakes in the structure or number of chromosomes in a developing baby. Chromosomes carry the genetic information needed for growth and development. These abnormalities can happen randomly and may lead to conditions like Down syndrome, where extra genetic material causes developmental differences. They can be detected through screening tests or diagnostic procedures during pregnancy. While some abnormalities result in health issues, others may have mild or no effects. Understanding and identifying these conditions helps expectant parents and healthcare providers plan for appropriate care and support.
