Deletion summary. Examples of microsatellite (D13S273, 6E3.2, D13S319, D13S272, and D13S25) and Southern (Rb1, p6E4.5, p9E4.3, p25b, and D13S25) analysis on key patients showing deletions in the 13q14.3 region. The table is divided into three sections with patients with karyotypic 13q deletions (del 13), karyotypic 13q translocations (t13), and patients not showing chromosome 13 rearrangement by cytogenetic analysis (karyotypically normal chromosome 13).
