Abstract
Prenatal diagnosis enables early diagnosis of congenital anomalies and genetic disorders in Utero. The population risk of having a child with congenital abnormality, whether genetically and/ or environmentally determined, varies between 3 and 5%. This risk increases several folds in families with a genetic disorder
Advanced imaging techniques as well as cytogenetic and molecular biology methods provide the means to diagnose prenatally numerous congenital structural malformations and genetic disorders in high-risk families.
Early diagnosis in utero can prove essential to prenatal and postnatal medical care, and treatment. It is also crucial to making informed decisions about continuing or terminating the pregnancy. Genetic counseling and prenatal diagnostic procedures constitutes a basic element of prevention of congenital anomalies and genetic disorders.
