Single-copy deletions of RPS19 and RPS26 in DBA probands. Log2 intensity ratio of SNP probes surrounding deletions of RPS19 on chromosome 19 (A) and RPS26 on chromosome 12 (B). The regions displayed include chromosome 19 from 46 100 000-48 100 000 and chromosome 12 from 54 400 000-55 000 000, corresponding to the boxed region in the chromosome ideogram above each panel. The region of single-copy loss is shaded. The locations of RPS19 and RPS26 are indicated by the vertical line through the deletion regions.
