Résumé
Over a period of 2 years, 86 couples [172 cases] were referred to the genetics clinic of the National Research Centre for premarital genetic counselling. About 73.25% had a family history of different genetic disorders. Consanguinity was found in 86.04%. Genetic investigations revealed chromosomal abnormalities in 26 cases [15.11%]; 23 cases [13.37%] had other abnormal results. After genetic counselling, postconceptional follow-up was carried out for 30 couples; 10 of them required amniocentesis that showed abnormal fetuses in 2 mothers. Other couples had normal offspring. We conclude that premarital genetic counselling is of great use in the detection of genetic disorders and is an essential step in changing attitudes towards premarital testing and reducing consanguineous marriage
