BTNL2 gene polymorphism and sarcoidosis susceptibility: a meta-analysis.

Abstract

BACKGROUND:

Butyrophilin-like 2 (BTNL2) rs2076530 gene polymorphism has been implicated in susceptibility to sarcoidosis. However, results from previous studies are not consistent. To assess the association of BTNL2 polymorphism and sarcoidosis susceptibility, a meta-analysis was performed.

METHODS:

PubMed, Embase were searched for eligible case-control studies. Data were extracted and pooled odds ratios (OR) with 95% confidence intervals (CI) were calculated.

RESULTS:

Ten studies involving a total of 3303 cases and 2514 controls were included in this meta-analysis. Combined data indicated that BTNL2 rs2076530 polymorphism was associated with sarcoidosis susceptibility in allelic model (A vs. G, OR = 1.59, 95%CI: 1.47-1.72), dominant model (AA + AG vs. GG, OR = 2.10, 95%CI: 1.67-2.65), and recessive model (AA vs. AG + GG, OR = 1.93, 95%CI: 1.49-2.50).

CONCLUSIONS:

This meta-analysis indicates that BTNL2 rs2076530 polymorphism contributes to the risk of sarcoidosis.
