Deletions involving RPS17 in DBA probands. (A) Log2 intensity ratio of SNP probes in the deletions adjacent to RPS17 on chromosome 15. The locations of 2 identical copies of RPS17 are indicated by the vertical lines. The identified region of copy loss is adjacent to RPS17; however, the paucity of probes, notably in the HumanOmniExpress chip (20QL and 1314), is apparent. (B) Log2 intensity ratios of CGH probes in the region of RPS17. Arrows at the top of the panel indicate the positions of RPS17. Gray points and connecting line depict a 30-kb median smoothing window. The region displayed is chromosome 15 from 79 450 000-83 800 000.
