Abstract

Objectives: The present study was designed to evaluate the association of transporters associated with antigen processing (TAP2) polymorphisms TAP2-379Ile > Val (rs1800454), TAP2-665Thr > Ala (rs241447) and TAP2-565Ala > Thr (rs2228396) as a candidate gene with susceptibility to the Systemic Lupus Erythematosus (SLE).

Methods: To analyze these three polymorphic variants, 88 patients with SLE and 100 healthy controls from northeastern Iran were enrolled from May 2018 to July 2019. Genomic DNA polymorphisms were performed by amplification refractory mutation system-polymerase chain reaction (ARMS-PCR) technique. Data were analyzed by SPSS software.

Results: In this cross-sectional study, there was a stratification between patients and controls. The distribution of the frequency of Ala73 (41.5%) allele at TAP2/665 and Ile 19 (10.8%) allele at TAP2/379 was higher in patients. Additionally, the Ala/Ala 13(14.8%) and Ala/Thr 49(55.7%) genotypes distributions at 665 positions were higher in SLE patients compared to the controls. Furthermore, frequencies of TAP2*H allele significantly increased in SLE patients 10(5.71%) (P=0.01). Frequency of TAP2*A allele in the control group was 120(60%) (p=0.06) due to the dominant genetic model. This allele has a protective effect against SLE. There was no relationship between TAP2*D, TAP2*E, TAP2*F and TAP2*G alleles with the outbreak of SLE.

Conclusion: Our data indicated that genetic variants in TAP2 gene may be associated with SLE disease. A correlation between Ala allele at TAP2/665 and Ile allele at TAP2/379 polymorphisms and pathogenesis of SLE was observed. Read now: https://bit.ly/3SduJbq
