- A 37-year-old woman with a balanced reciprocal translocation was found to have a high-risk non-invasive prenatal screening test indicating potential chromosome 18 abnormalities during her 13th week of pregnancy.
- Advanced techniques including cytogenetic analysis, FISH, and SNP-array were used to analyze her amniotic cells, revealing duplications on chromosome 18 and chromosome 9, suggesting aneuploidies.
- The study emphasizes the importance of using a combination of NIPT and detailed cytogenetic approaches to accurately detect and confirm chromosomal anomalies in high-risk pregnancies.
