高中性粒细胞计数可能会因果性地增加带有或没有裂口 (NSCL/P) 的非综合性裂口的风险. 这项研究发现白细胞计数与NSCL/P之间存在遗传联系,强调中性粒细胞是关键因素.
科学领域:
- 遗传学和免疫学研究.
- 调查出生缺陷的遗传基础.
背景情况:
- 孕产妇的炎症与非综合征性裂唇 (有或没有裂口) (NSCL/P) 的风险增加有关.
- 白血球数量是炎症的指标,与NSCL/P风险相关性尚未得到充分探索.
研究的目的:
- 研究各种白细胞计数与NSCL/P.L.风险之间的遗传关系.
- 确定特定白细胞计数是否与NSCL/P有因果关系.
主要方法:
- 利用来自NSCL/P病例和对照组的全基因组关联研究 (GWAS) 数据.
- 在6个白细胞计数 (WBC,NC,MONO,LYM,EOS,BASO) 上进行了基因相关性,重叠和门德尔随机化 (MR) 分析.
- 确定了类基因位置和丰富的基因,专注于使用MR的因果推理.
主要成果:
- 在白细胞计数 (WBC) 和NSCL/P之间观察到显著的遗传相关性.
- 鉴定了24个类位,GSDMA在17q21.1显示强烈的类位.
- 门德尔随机化表明,较高的中性粒细胞计数显著增加NSCL/P风险 (OR=2.48,P=5.41E-3).
结论:
- 在白细胞计数和NSCL/P之间存在遗传相关性和共享的白细胞位.
- 有证据表明,中性粒细胞数量升高在NSCL/P发育中的潜在因果作用.
- 这些发现强调了中性粒细胞作为NSCL/P病变发生的潜在因素.

Disorders of Leukocytes
Leukopenia may result from bone marrow disorders, autoimmune diseases, and infectious diseases. For example, conditions such as multiple myeloma and aplastic anemia can impair the bone marrow's ability to produce adequate leukocytes. Similarly, autoimmune diseases like lupus and viral infections such as HIV can prompt the immune...
