C4 and 21-hydroxylase gene deletions in nasopharyngeal carcinoma among the Chinese.
Deletions around the C4 and 21-hydroxylase (21-OH) gene region occur among the Chinese, and C4B together with 21-OHA deletion is the most common. This deletion was found to be strongly associated with human leucocyte antigen (HLA) B58 DRB1*0301, particularly with DRB1*0301. The initial observation of a high frequency of this deletion in nasopharyngeal carcinoma (NPC) was secondary to the B58 DR3 association with NPC. A deletion of 21-OHA alone was observed to be associated with HLA B13 DRB1*1501.
