This may be because PART1 is located on chromosome 5q12, a region that is usually lost in oral squamous cell carcinoma (OSCC) and head and neck squamous cell carcinoma (HNSCC) (Abou-Elhamd & Habib, 2008; Noutomi et al., 2006). The gene discussed is PART1; the disease is head and neck squamous cell carcinoma.
