Figure 2. Family pedigrees showing segregation analysis of USH2A deletions identified in this study. A: Segregation analysis of the USH2A deletion involving exons 9-14 (del ex 9-14) performed in available DNA samples from family FRP-429. B: Segregation analysis of exon 14 USH2A deletion (del ex 14) performed in available DNA samples from family FRP-404. C: Segregation analysis of deletion involving exons 5-13 (del ex 5-13) of USH2A in family FRP-298. D: Segregation analysis of the USH2A mutations p.R2723X and deletion of exons 1-4 (del ex 1-4), performed in available samples from family FRP-323. E: Segregation analysis of the USH2A mutations p.5540dupA and deletion of exons 5-9 (del ex 5-9), performed in both affected patients from family FRP-413. F: Segregation analysis of the USH2A mutations p.C759F and deletion of exons 22-29 (del ex 22-29), performed in available DNA samples from family FRP-423.
