Genetic Zygosity Analysis for Fetal Inborn Errors of Metabolism (Screening)

What This Test Measures

This test assesses the genetic makeup (zygosity) of specific genes linked to inborn errors of metabolism. It looks for mutations that could cause metabolic disorders, which may require special care or treatment. The test typically involves analyzing a small sample of fetal cells, often obtained through procedures like chorionic villus sampling (CVS) or amniocentesis.

Why It’s Done

Your healthcare provider may recommend this test if you’re at higher risk for certain genetic conditions, based on family history, ethnicity, or other factors. It helps determine if your baby has inherited a recessive genetic trait that could lead to metabolic issues.

How the Test Works

The test involves analyzing DNA from fetal cells to check for specific genetic variations (mutations) associated with metabolic disorders. Results are reported as either 'homozygous,' 'heterozygous,' or 'wild-type' (normal), indicating the likelihood of the baby inheriting the condition.

What the Results Mean

Results help guide next steps, such as monitoring your baby’s health closely, recommending specialized care, or planning for potential interventions if the condition is confirmed later. Some results may require further testing or genetic counseling.
