Popis: The data provided are given as an illustration of molecular-cytogenetic approach for improvement of prenatal cytogenetic diagnosis of rare chromosomal abnormalities. The main indication for prenatal karyotyping discussed herein presented with increased nuchal translucency at 10–14 weeks of gestation. The following rare chromosomal abnormalities were revealed by FIASH: microdeletion 22q11.2, r(13)(p11q22), dup(8)(p23p12), del (13)(q34), invdupY(q10), two sSNMCs of 5 and 20 chromosomes origin. The importance of improving and systematizing of the ultrasonographic diagnosis of “mild” developmental defects, providing of the expanded prenatal molecular studies and contemporary FISH-technique application is emphasized.
