Evaluation of the results of patients who applied to the Çukurova University, Medical Genetics Department for prenatal diagnosis and determination of genetic counseling principles

BACKGROUND/AIM: The aim of this study was to summarize the experiences of a single medical center for genetic diagnosis and treatment of prenatal patients. MATERIALS AND METHODS: This study includes a retrospective data analysis of 2843 prenatally investigated cases using invasive methods during a 6-year period (2013–2019) at a single tertiary care center. RESULTS: Chromosomal abnormalities were detected in 80 out of 1221 amniotic fluid samples;,178 out of 1608 chorionic villus samples, and 1 out of 14 cordocentesis samples. The most common chromosomal abnormality was trisomy 21. At least one mutation was detected in 63 of the 152 molecular tests performed on fetuses. CONCLUSION: Clinical procedures such as ultrasounds and genetic tests are able to provide a better clinical follow-up for pregnant women about the possible congenital anomalies or any genetic condition, with proper genetic counseling and testing methodology.
