概括

膝关节骨关节炎 (OA) 存在的遗传标记不能预测疾病的进展. 然而,有19种新的单核酸多态 (SNP) 与膝盖骨关节炎患者的关节空间缩小有显著关联.

科学领域:

遗传学是一个遗传学.
整形外科整形外科整形外科
生物标志物生物标志物

背景情况:

膝关节关节炎 (OA) 是一种复杂的疾病,其进展模式各异.
已知OA存在的基因组标记物,但它们在疾病进展中的作用尚不清楚.

研究的目的:

为了确定与膝关节OA进展的遗传关联.
评估多基因风险评分 (PRS) 对膝关节OA进展的预测值.

主要方法:

在24个月内对297名膝关节OA患者的IMI-APPROACH队列进行了分析.
膝关节OA进展通过关节空间宽度 (minJSW),疼痛 (KOOS) 和放射性OA进行评估.
对30个先前识别的OA相关SNP和PRS结构的全基因组关联分析.

主要成果:

现有的OA风险SNP和膝盖OA进展之间没有发现显著的关联.
该PRS没有显示膝盖OA进展的预测值.
十九种新型变体与最小关节空间宽度的显著减少有关 (P <5x10−8).

结论:

已建立的OA风险SNP,单独或在PRS中,不能预测膝盖OA的进展.
19个新的SNP与关节空间缩小有关,这表明了潜在的生物标志物.
生物信息学工具可以优先考虑OA进展的潜在生物标志物,即使数据有限.

Genome-wide Association Studies-GWAS

Genome-wide Association Studies-GWAS

Genome-wide association studies or GWAS are used to identify whether common SNPs are associated with certain diseases. Suppose specific SNPs are more frequently observed in individuals with a particular disease than those without the disease. In that case, those SNPs are said to be associated with the disease. Chi-square analysis is performed to check the probability of the allele likely to be associated with the disease.
GWAS does not require the identification of the target gene involved in...

Knee Joint

Knee Joint

The knee joint is the most complicated joint in the body. It consists of three articulations– two tibiofemoral and one patellofemoral. As is characteristic of synovial joints, the knee joint has a thin articular capsule that partially surrounds this joint cavity. Additionally, several ligaments, muscles, and cartilaginous structures support the movement of the knee.
A total of seven ligaments support the knee joint. The patellar ligament, which is also attached to the quadriceps femoris...
