Abstract:
Objective:To clarify the characteristics of the A20 regulatory changes by analyzing mutations in the non-coding region of the A20 gene in patients with T-cell lymphoma leukemia (T-LCL) .
Methods:PCR and nucleotide sequence analysis were used to detect mutations in the non-coding region of the A20 gene, and DNA samples from PBMCs of 52 cases of T-LCL and 99 healthy controls.
Results:A missense mutation (c.-672T>G) was detected in the A20 gene promoter from one T-LCL patient, which has been registered as a SNP (rs139054966) in gene bank. Meanwhile, a new mutation was detected in the 3′ UTR mRNA (3916 (C>G) ) . These two mutations were absent in other T-LCL samples and controls.
Conclusion:The rs139054966 (c.-672T>G) and 3916 (C>G) mutations in the A20 gene were detected in T-LCL patients for the first time. There was also rs139054966 located on the binding region of the transcription factor P53, and its significance remained to be further clarified.
