Although the study did not elaborate in detail on the normal biological function of FRG1BP, its disruption in the context of dic(9;20) translocations highlights its potential role as a candidate target locus whose alteration could contribute to leukemogenesis."}, {"type": "fg", "children": [{"type": "fg_f", "ref": "1"}]}, {"type": "t", "text": ""}, {"type": "p", "children": [{"type": "t", "text": "\nWhile the precise physiological role of FRG1BP remains to be fully elucidated, the mapping of chromosomal breakpoints near its 3′ region suggests that its normal function might be linked to maintaining genomic integrity or regulating gene expression.
