摘要: A characteristic translocation t(2;13)(q35;q14) has been previously identified in the pediatric soft tissue tumor alveolar rhabdomyosarcoma. We have assembled a panel of lymphoblast, fibroblast, and somatic cell hybrid lines with deletions unbalanced translocations involving chromosome 2 to develop physical map distal 2q region. Twenty-two probes were localized on this by Southern blot analysis mapping panel. The position these respect t(2;13) rhabdomyosarcoma breakpoint was then determined quantitative an line two copies derivative 13 one copy clones derived from line. demonstrate that is situated within interval delimited deletion fibroblast GM09892 t(X;2) GM11022. Furthermore, comparison our data linkage syntenic region mouse 1, we conclude most closely flanked loci INHA ALPI interval.
