Intrauterine growth retardation/restriction (IUGR) implies that fetal growth is being inhibited and that fetus does not attain its growth potential. Prenatal diagnosis enables early diagnosis of congenital anomalies and genetic disorders in utero. Thirty-eight high-risk pregnancies whose gestational age ranged from 14 to 30 weeks with a mean gestational age of 20.05 were selected. Chromosome analysis and cytokinesis-block micronuclei assay were performed. The mean CBMN frequency of study subjects was 13 and the control subjects showed 10.14 (p < 0.05). Chromosome analysis revealed 65.78% of normal karyotype and 34.21% abnormal karyotypes. The abnormal karyotypes include 92.30% of numerical abnormalities and 7.69% structural abnormalities. The incidence of abnormal karyotype and CBMN frequency increased with increased paternal and maternal age, duration of married life, previous history of abortion and IUGR, socioeconomic status, etc. Genetic counseling in association with modern prenatal diagnostic procedures constitutes a basic element of prevention of congenital anomalies and genetic disorders. The magnitude of the risk of occurrence, the impact of the disease on the patient and family, and the anticipated future developments are the main informations conveyed during genetic counseling. Hence from the present study, it can be concluded that proper diagnosis of chromosomal abnormalities can lead to the prevention of future birth of similarly affected children. This can be achieved by instituting genetic counseling. Parents with an IUGR fetus should be counseled that their neonates may have some immediate complications at birth but also some long-term complications including impaired cognitive function such as learning disabilities and spastic cerebral palsy. |
