Cancer : 9p Rearrangements in ALL
Cancer Name 9p Rearrangements in ALL
Clinics and Pathology
Disease acute lymphocycic leukemia (ALL)
Epidemiology approximately 10% of childhood ALL, similar in adult ALL
Prognosis recent data indicate that an abnormal 9p is an adverse risk factor for B-lineage, but not T-lineage pediatric patients; this is more pronounced in standard-risk patients (age 1 - 9 years with WBC count <50 X 109/l); a dic(9;12)(p11-13;p11-12) has been reported to have a very low relapse rate
Related Genes
Gene Symbol CDKN2A
Description " the different types of 9p aberrations may have different molecular consequences; when a deletion of 9p occurs, the genes involved colud be MTS1/CDK4I/p16INK4A(CDKN2) and MTS2/p15INK4B(CDKN2B); these are believed to be tumor suppressor genes, and loss of heterozygosity occurs more frequently than cytogenetic deletions of 9p; however, mutation of the remaining allele is infrequent, and methylation changes may cause inactivation of the remaining allele.
