Result: The frequencies of SNP
G155391A were counted and compared among samples from Guangdong in South China, which is an
NPC endemic region, as well as in North China and Europe, where
NPC incidence is relatively low.
Result: The increasing trend in the frequency of SNP
G155391A in samples from regions with low to high
NPC incidence was consistently observed in
NPC patients, using either TW or TB samples (both P < 0.001; Table 5).
Result: The result revealed a consistently strong association between SNP
G155391A and a high
NPC
