Özet
Chromosomal abnormalities are a major cause of mental retardation and/or multiple congenital anomalies (MCA/MR). Screening for these chromosomal imbalances has mainly been done by standard karyotyping. The objective of this study was to report standard chromosome analysis and FISH screening of a series of 24 patients with MCA/MR. Structural chromosomal abnormalities were detected in 24 alterations and included 5 deletions, 2 duplications, 6 unbalanced translocations, 3 inversions, 2 insertions, 3 derivative chromosomes, 2 marker chromosomes and 1 isochromosome. We confirm that a high percentage of MCA/MR cases hitherto considered idiopathic is caused by chromosomal imbalances. We conclude that patients with MCA/MR should be routinely karyotyped.
