The LMP1 30-bp deletion variant (as represented in Lane C, Figure 1) was found in 19/34 cases (55.9%) of which 13 were undifferentiated carcinoma (type III) and 5 were non-keratinizing carcinoma (Type II) and 1 was keratinized squamous carcinoma (type I). This evidence concerns the gene PDLIM7 and undifferentiated carcinoma.
