BTNL2 Gene Polymorphism and Sarcoidosis Susceptibility: A Meta-Analysis

چکیده
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.

The BTNL2 G16071A gene polymorphism increases granulomatous disease susceptibility
OBJECTIVE The butyrophilin-like 2 (BTNL2) G16071A gene polymorphism has been implicated in the susceptibility to granulomatous diseases, but the results were inconclusive. The objective of the current study was to precisely explore the relationship between BTNL2 G16071A gene polymorphism and granulomatous disease susceptibility by the meta-analysis including false-positive report probability (F...

Background: In 10-30% of the cases with sarcoidosis, skin lesions appear solely without any systemic signs or symptoms. BTNL2 gene, which is a member of the immunoglobulin gene super family and is associated with CD86 and CD80 co-stimulatory receptors, is identified to play an important role in the establishment of sarcoidosis. We aimed to evaluate the role of this gene in patients with skin sa...

BACKGROUND Sarcoidosis is a polygenic immune disorder disease with predominant manifestations in the lung. BTNL2 gene polymorphisms were previously linked to susceptibility to sarcoidosis. Relationships between sarcoidosis and cancers have been suspected for a long time but little evidence has been reported until now, and recent works show a link between butyrophilin family proteins and anti tu...

Background and Aim: Sarcoidosis is a non-caseous granulomatous disease that can involve several organs such as lung, kidney, liver, heart and skin. In systemic sarcoidosis, skin lesions occur in 20-35% of patients. Cutaneous sarcoidosis with no systemic involvement was found in about 25% of patients. Mutation within Butyrophilin-like 2 (BTNL2) gene, rs2076530 was reported in systemic sarcoidosi...

BACKGROUND/AIM Sarcoidosis is a complex, multifactorial immune disorder with unknown etiology. A single nucleotide polymorphism (G→A, rs2076530) in the butyrophilin-like 2 (BTNL2) gene results in a truncating protein formation. It has been previously reported that this variation may be a risk factor for sarcoidosis in certain ethnic groups. This study was conducted to determine whether there is...
