Figure 1From: Genetic investigations on 8 patients affected by ring 20 chromosome syndrome FISH analysis with chromosome 20-specific α-satellite DNA probes. FISH results on r(20), indicating alphoid-specific heteromorphism suitable to discriminate between the two homologous chromosomes 20 (arrowed) in DG, CD, PE and FMA patients. In FL, BV and BD no polymorphic signals on chromosome 20 homologous have been identified. See text for explanationBack to article page
