D. Vanopstal et al., APPLICATION OF FLUORESCENT IN-SITU HYBRIDIZATION FOR DE-NOVO ANOMALIES IN PRENATAL-DIAGNOSIS, Prenatal diagnosis, 13(9), 1993, pp. 825-832
Fluorescent in situ Hybridization (FISH) was carried out for three cas
es of abnormal karyotypes in prenatal studies. Two concerned de novo s
tructural anomalies and the third a marker chromosome. The origin of t
he extra material could be defined in all three cases, which gives a b
etter insight into the relationship between genotype and phenotype and
makes more adequate genetic counselling possible.
