GENETIC DISORDERS
Genetic defects may occur either as a single gene defect or genetic syndromes. The commoner of the two groups are the single gene defects with examples as Tay-Sachs in the Jewish population, Sickle Cell disease in African-Americans and Latinos and Cystic Fibrosis in Caucasians.
Some couples may be carriers of genetic disorders for which prenatal diagnosis can be performed. In our centre, the commonest single gene defect diagnosed is the sickle cell disease.
