概括

患有复杂表型的Gaucher病 (GD) 患者通常具有额外的遗传性疾病. 识别这些并发性疾病对于个性化治疗和精准医学中改善患者结果至关重要.

科学领域:

遗传学是一个遗传学.
精准医学是一门精准的医学.
罕见疾病罕见疾病

背景情况:

氏病 (GD) 呈现显著的表型异质性,即使在具有相同GBA1基因型的患者中也是如此.
葡萄糖胺 (GlcCer) 在GD中的积累引发慢性炎症,通过与其他生物通路的相互作用影响疾病表达.
为GD开发了一种精准医学模型,GD是一种原型单基因疾病.

研究的目的:

将精准医学框架应用于复杂表型的高氏病患者.
调查其他遗传疾病在修改GD表现和管理中的作用.
为了确定异常呈现的GD患者的并发遗传诊断.

主要方法:

利用来自第三级护理中心的纵向跟踪GD患者队列.
综合整体外体序列测序 (WES) 具有详细的临床信息.
应用了精准医学框架,包括临床推理,深度表型,基因组整合和个性化治疗,对17名患者的子集.

主要成果:

在275名GD患者中,17名 (6.2%) 患有非典型的表型,仅由GD无法完全解释.
在这些患者中,WES确定了额外的遗传诊断,包括遗传性血色素变体 (n=5),家族地中海热 (n=4),MSH6与突变相关的遗传癌症倾向 (n=2),和自身主导多囊性病 (ADPKD) (n=2).

结论:

同时存在的遗传性疾病可以显著改变高氏病的临床表现和管理.
这项研究推进了精准医学策略,以优化复杂GD病例的结果.
对GD遗传和表观遗传修饰物的进一步研究对于完善个性化治疗方法至关重要.

Pharmacogenomics: Identification of New Drug Targets

Advances in genomics have profoundly influenced drug discovery by increasing both the speed and accuracy of pharmaceutical development. Pharmacogenomics, which examines how genetic variation influences drug response, facilitates the identification of novel therapeutic targets and enables patient stratification for personalized treatment. These strategies contribute to improved drug efficacy, minimized adverse effects, and more efficient clinical trial design.Mapping genetic differences...
