SouthSeq is a research study looking at how a new kind of genetic test, called whole genome sequencing, can be used to try to find the reason for medical problems among newborns in a neonatal intensive care unit (NICU).
The whole genome sequencing test looks at a person’s entire genetic code. The test looks for a genetic change that may be the cause of a medical problem. We believe doing this test in a NICU can allow diagnoses to be made earlier and may help doctors provide better care and treatments.
To be included in the study, a newborn must have medical problems or unusual physical findings that may have a genetic cause. Results from the whole genome sequencing test will be given back to families and their doctors. Results may include:
- The reason for the newborn’s medical problems or unusual physical findings.
- Other genetic changes that may be important for the family’s medical care.
Genes and the Genome
Genes are the sections of DNA that provides instructions for the human body to grow and work properly. A human genome contains about 22,000 genes. All of a person’s DNA is called his or her genome.
All people have changes in their DNA. Genetic changes can range from very small to very large. Most genetic changes are not related to a medical problem. Some changes are harmful and cause disease. These are the types of changes we look for in this study.
