B-ALL Tables: Prognostic Genomic Abnormalities and Recurrent Gene Fusions (view source)
Revision as of 13:22, 22 July 2021
, 13:22, 22 July 2021Added other B-ALL table
'''Table 1 - Gene fusions reported in Ph-like B-ALL and other new B-ALL molecular subtypes (Literature Review)'''. Table derived from Akkari et al., 2020 [PMID 32302940] with permission from Cancer Genetics.
'''Table 1 - Prevalence and prognosis of B-ALL genomic abnormalities in the pediatric and adult population for all categories reported to date.''' Of the Ph-like category, only CRLF2 and ABL1-class rearrangements are indicated. Table derived from Akkari et al., 2020 [PMID 32302940] with permission from Cancer Genetics. All percentages are approximate.
