Approximately 70-80% of T-PLL karyotypes are complex, which is considered minor diagnostic criteria, and usually include 3-5 or more structural aberrations. Common cytogenetic abnormalities include those of chromosome 8, such as idic(8)(p11.2), t(8;8)(p11.2;q12), and trisomy 8q. Other frequent changes are deletions in 12p13 and 22q, gains in 8q24 (MYC), and abnormalities in chromosomes 5p, 6, and 17.<ref name=":5" /> | Approximately 70-80% of T-PLL karyotypes are complex, which is considered minor diagnostic criteria, and usually include 3-5 or more structural aberrations.
