What does MCC (Maternal Cell Contamination) mean and why is it important?

MCC refers to the presence of maternal cells in a fetal sample, which can interfere with the accuracy of prenatal genetic testing. Since fetal samples are often collected from the placenta or amniotic fluid, there is a possibility that maternal DNA may be mixed with fetal DNA. MCC analysis identifies and accounts for this contamination, ensuring that the results truly represent the fetal genetic profile. This step significantly improves the reliability of the test.

How is the sample collected for this tePrenatal Single Mutation Confirmation by Sanger Sequencing with MCC test?

The sample is typically obtained through procedures such as amniocentesis or chorionic villus sampling (CVS), depending on the stage of pregnancy. These procedures involve collecting a small amount of amniotic fluid or placental tissue under medical supervision. The collected sample is then sent to a laboratory for DNA extraction and analysis.

How does Sanger sequencing work in this prenatal test?

Sanger sequencing works by reading the exact order of DNA bases in a targeted region where the mutation is suspected. The DNA from the fetal sample is amplified and sequenced, allowing specialists to identify whether the mutation is present. This method provides a clear and accurate representation of the genetic sequence, making it ideal for confirming specific mutations.

What types of mutations can this test confirm?

This Prenatal Single Mutation Confirmation by Sanger Sequencing with MCC test is designed to confirm specific genetic changes such as single nucleotide variations, small insertions, and deletions within a targeted gene region.
