TP53 and leukemia: Together with significantly higher proportions of 5q and 7q deletions in XP-C leukemia (P = 1.024e−06 for 5q and P = 0.002985 for 7q deletions, Fisher’s exact test, two-sided), this may indicate that the studied leukemia cases are close to TP53 mutated with complex karyotype subgroup according to Papaemmanuil et al.16.
