Long Non-coding RNA LINC-PINT and LINC00599 Polymorphisms are Associated With High-altitude Pulmonary Edema in...

High-altitude pulmonary edema (HAPE) is a kind of non-cardiogenic edema with high incidence and life-threatening. This study was designed to explore the association of LINC-PINT and LINC00599 polymorphisms with HAPE susceptibility.

This study included 244 HAPE patients and 243 age-, sex-matched healthy controls from the Chinese population. The genotypes of polymorphisms were detected using the Agena MassARRAY. The relationship between polymorphisms and HAPE risk was evaluated using a χ² test with an odds ratio (OR) and 95% confidence intervals (CIs) in multiple genetic models.

We observe a significant association between the rs157928 and decreased HAPE risk in genotype model (OR=0.65, 95% CI=0.43-0.98, p=0.038). The subgroup analysis results indicated that rs2272026 was associated with a decreased risk of HAPE in younger patients with age ≤32 (codominant model: p=0.006; recessive model: p=0.005 additive model: p=0.018; and allele model: p=0.012; rs72625676, codominant model: p=0.038; recessive model: p=0.037). Among patients older than 32 years, there was a significantly increased risk of HAPE associated with the rs2272026 and rs1962430 (rs2272026: genotype model: p=0.049; recessive model: p=0.029; rs1962430: genotype model: p=0.024; recessive model: p=0.020). Nevertheless, rs157928 had relationship with significantly reducing the risk of HAPE in the genotype model (p=0.018).

Our study suggests that LINC-PINT and LINC00599 polymorphisms are associated with HAPE susceptibility in Chinese population.
