When it comes to prenatal screenings, many people are familiar with tests for conditions like Down syndrome, but microdeletions are less commonly discussed. So, what exactly is a microdeletion?
A microdeletion occurs when a small segment of a chromosome is missing. Think of it as a tiny piece of DNA that’s been “deleted.” Our bodies are made up of cells that contain chromosomes, which hold DNA inherited from our parents. Typically, we have 46 chromosomes—23 from each parent. During cell division, sometimes a minute section of a chromosome can be lost, leading to what we call a microdeletion.
The implications of a microdeletion can vary widely based on its size and location. While some microdeletions may result in health issues or developmental delays, others may have little to no effect. This is why understanding how microdeletions are detected during pregnancy is essential for expectant parents.
Detection of Microdeletions During Pregnancy
Prenatal tests can identify microdeletions, and knowing about them in advance allows parents to prepare. For example, some non-invasive prenatal testing (NIPT) options may screen for these abnormalities. If you receive a positive result, it’s important to discuss the next steps with your healthcare provider to better understand what it might mean for your baby.

Conclusion
In summary, microdeletions are chromosomal abnormalities where a small piece of DNA is missing, and while they can lead to health challenges, not all will. Prenatal testing can help identify these issues early on, allowing parents to prepare for what’s to come.
