93800-1
Laboratory1p/1q chromosome deletion [# Ratio] in Tissue by FISH
Definition
The ratio of chromosome 1p arm deletions to chromosome 1q arm deletions. Results are used to diagnose oligodendroglioma brain tumors and to determine best treatment options. Tumors with 1p/1q ratio <0.80 and ≥24% deleted cells are deemed deleted for 1p.
