概括

在33%的早期发作的系统性红斑狼 (SLE) 儿科患者中发现了单一的原因. 研究这些遗传因素对于更好的疾病管理和SLE儿童的遗传咨询至关重要.

科学领域:

遗传学是一个遗传学.
免疫学免疫学免疫学
儿科儿科儿科

背景情况:

系统性红斑狼 (SLE) 是一种复杂的自身免疫性疾病.
儿科患者早期发病的SLE往往在诊断和管理方面带来独特的挑战.
识别潜在的遗传因素可以提供有关疾病发病的见解.

研究的目的:

调查早期发病SLE的儿科患者中单源性病因的流行率.
为了确定与早期发病的SLE相关的特定基因突变.
在这个患者队列中探索基因型-表型相关性.

主要方法:

整体外体序列测序 (WES) 在15例儿科SLE病例的基因组DNA上进行,病例发病早期 (≤6岁).
患者符合系统性狼国际合作诊所 (SLICC) 的标准.
使用桑格测序证实了致病变体.

主要成果:

在15名患者中有5名 (33.3%) 检测到显著的基因突变.
鉴定了DNASE1L3,ACP5,IFIH1和C1S中的突变,与各种临床表现有关,包括皮肤,脏和血液参与.
所有确定的患者都对治疗有反应,达到较低的SLEDAI得分.

结论:

在早期发病的SLE患者中,显著的比例存在单一性原因.
建议对遗传病因进行调查,以改善儿科SLE的管理和遗传咨询.
需要进一步的多中心研究来巩固基因型-表型关联.

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...
