DLC1 is unlikely to be a primary target for deletions on chromosome arm 8p22 in head and neck squamous cell carcinoma.

Allelic imbalance on chromosome arm 8p is common in head and neck squamous cell carcinoma (HNSCC). DLC1, a tumour suppressor gene inactivated in liver carcinogenesis and encoding a Rho GTPase activating protein (RhoGAP) maps to one of the deleted regions (8p21.3-22).
