Hereditary diseases are those passed from parents to children through genes. In these cases, parents carry a mutation that can cause severe diseases when transmitted to their children. There are different types of inheritance and severity in their expression, but many are diagnosable and can be avoided. The most common ones are Cystic Fibrosis, Thalassemias, and Muscular Dystrophy. These and many others can be detected by the PGT-M technique or Preimplantation Genetic Diagnosis for monogenic diseases. However, genetic diseases associated with advanced maternal age or that cause repeated miscarriages are much more frequent. In this group, the most common include Down syndrome, Edwards syndrome, Patau syndrome, and other more complex anomalies. These are detected by Smart PGT-A Plus or Preimplantation Aneuploidy Genetic Testing. This test is also used as a screening tool in women over 37 years old who want to ensure the transfer of a healthy embryo, reducing abortion rates and shortening reproductive timelines.
