Fig. 2From: Molecular and cytogenetic analysis of small supernumerary marker chromosomes in prenatal diagnosisThe FISH results of Case 2, 5, and 18. A In Case 2, two DXZ1 signals were observed, and one signal was found at the sSMC. B In Case 5, two chromosome 12 showed normal 12pter/12qter signals, and two additional 12pter signals were observed at the sSMC. C In Case 18, three signals specific for 21q22.13-21q22.2 region were observedBack to article page
