Chromosomal Abnormalities

Chromosomal abnormalities refer to changes in the number or structure of your chromosomes. Chromosomes are tiny, thread-like structures found inside almost every cell of your body. They are made of DNA and contain all the genetic instructions that tell your body how to develop and function. When there's an abnormality, it means there's either too many or too few chromosomes, or a piece of a chromosome is missing, extra, or arranged incorrectly. These changes can impact a person's health, development, and bodily functions in various ways. Most chromosomal abnormalities occur randomly, meaning they are not inherited from parents but rather happen by chance during the formation of egg or sperm cells, or very early in fetal development. This process is often beyond anyone's control. While some specific types can be inherited, and factors like advanced maternal age can increase the risk for certain conditions, the majority are spontaneous events. It's important to understand that these changes are typically not caused by anything a parent did or didn't do. Lab tests, such as karyotyping, chromosomal microarray, or Non-Invasive Prenatal Testing (NIPT), are crucial for diagnosing chromosomal abnormalities. These tests analyze your chromosomes to identify any changes. Receiving a diagnosis helps your healthcare team understand the specific condition, its potential health implications, and allows them to provide appropriate medical care, support, and genetic counseling. It also helps families prepare for future challenges and make informed decisions regarding their health and reproductive planning.
