Prenatal genetic diagnosis of hereditary diseases
More than 1.000 hereditary diseases can be prenatally diagnosed in those pregnancies in which:
- Biochemical or echographic parameters point out the possibility of a genetic disease in the fetus.
- Family history indicates the presence of a hereditary disease, but it has not been genetically identified.
PTo carry out these studies, besides sending the non cultured chorionic villi or amniotic liquid, it is highly recommended to culture a portion of the fetal sample, just in case more DNA is required to complete the analysis.
This is especially important when analyzing large genes or diseases in which several genes are involved.
