ANEUPLOIDY SCREENING BY FLUORESCENT IN SITU HYBRIDISATION METHOD IN THE INTERFASE CELLS

Abstract

Introduction: Numerical and/or structural chromosomal abnormalities in the fetus can be detected by prenatal diagnostic methods. Fetal karyotyping is one of the prenatal diagnostic methods which is usually performed after the 14th week of gestation. More than 99 % of all chromosomal abnormalities comprise the aneuploidies of five chromosomes. These five chromosomes are number 13, 18, 21, X and Y. Recently the development of Fluorescent in situ Hybridization (FISH) for the analysis of chromosome aneuploidies in interphase cells has provided rapid results and the duration of informing the familtes has been shortened. Materials and Methods: In this study, amniotic fluid sampling (AFS) of 30 pregnants, ageing between 20 and 46 year-old and studied by both classical cytogenetic technique and FISH. Results: The gestational period for the sampling process of these women is between the 14th and 32th week of pregnancy. The indications of cytogenetic study in AFS were advanced maternal age (AMA) in 16 cases, triple test result pointing to increased risk in 6 cases, abnormal ultrasound findings in 3 cases, AMA with triple test result in 1 case, AMA with abnormal ultrasound findings in 1 case, Down syndrome in the mother in 1 case, trisomy 21 in chorionic vİllus sampling in 1 case. Normal signalling in 27 cases and trisomy 21 in 3 cases were obtained by FISH. All results were obtained within 24 hours by FISH method and analysed by using classical cytogenetic method. Conclusion: In conclusion it is considered that FISH method can be used for getting rapid result besides clasical cytogenetic method in the.screening.of.the.most.common.aneuploidies.
