Chromosome region 17p13.1 deletion in Blood or Tissue by FISH

Chr 17p13.1 Del Bld/T FISH

Definition

  • Deletions at 17p13.1 involving the TP53 gene can be detected by FISH and used for the diagnosis of chronic lymphocytic leukemia (CLL), multiple myeloma as well as other forms of cancer. Labs will report the number of cells that have the probe deletion out of total number of cells examined (e.g. 80 out of 100 cells, or 80%). Results are typically reported in ISCN (International System for Human Cytogenetic Nomenclature) format [LOINC: 62356-1]. This term is based, but not limited in use to, the Vysis LSI p53 (17p13.1) probe, which targets the TP53 gene and flanking regions.
