Spina Bifida Genetic Testing Explained
Spina Bifida Genetic Testing Explained Spina bifida genetic testing gives parents-to-be and others important info about possible spinal defects before birth. It’s a key part of prenatal care. By screening for spina bifida and doing genetic tests, we can spot genetic signs that might mean a risk.
This helps us take steps early to help the child. Knowing about these signs is key to caring for the child’s health. Spinal defect tests are very important. They help parents and doctors get ready for what’s ahead.
Introduction to Spina Bifida
Spina bifida is a condition where the spinal cord and its cover don’t fully form. It’s a type of neural tube defect. Doctors can often spot it early thanks to better prenatal care and tests.
What is Spina Bifida?
Spina Bifida Genetic Testing Explained Spina bifida happens when the neural tube doesn’t close fully in the womb. This can cause problems like trouble moving, learning issues, and problems with the bowels or bladder. It means the spine and spinal cord didn’t form right.
Types of Spina Bifida
There are three main types of spina bifida, each with its own level of severity:
- Spina Bifida Occulta: This is the mildest type, where a small gap exists between some vertebrae.
- Meningocele: This type has a sac of fluid coming out of the baby’s back. It holds the membranes around the spinal cord but not the cord itself.
- Myelomeningocele: This is the most severe form, where the spinal cord and its cover come out through an open spine. It can lead to big disabilities.
Causes and Risk Factors
We don’t know exactly why spina bifida happens, but some things increase the risk. Genetics, not having enough folic acid early in pregnancy, and some medicines or health issues in the mom can play a part. Spina Bifida Genetic Testing Explained
Knowing about spina bifida symptoms and risk factors helps us prevent it and act fast if it happens. Spotting the chance of neural tube defects early makes managing spina bifida better.
