概括

遗传视网膜退化 (IRD) 基因型的人口透率低于预期. 这表明疾病表现需要遗传或环境因素,影响IRDs的遗传测试和治疗开发.

科学领域:

遗传学是一个遗传学.
眼科医生眼科眼科
生物信息学是一种生物信息学.

背景情况:

遗传性视网膜退化 (IRDs) 是工作年龄成人失明的主要原因.
IRD通常被认为是具有高透性的单一产物.
表型鉴定可能会高估IRD透率,并掩盖基因型-表型谱.

研究的目的:

量化IRD相关变异在人群层面的透率.
在大型生物库中确定IRD基因型的真实流行率.
评估遗传和环境因素对IRD表现的影响.

主要方法:

在我们所有人 (AoU) 生物库中选了317,964名参与者,以检测IRD变体.
策划了一个具有IRD兼容基因型的队列.
定义的嵌套国际疾病分类 (ICD) -9/10代码集通过疾病注释频率 (DAF) 估计透率.
使用来自英国生物库 (UKB) 的视网膜成像数据验证的结果.

主要成果:

在AoU队列中的DAF从9.4% (IRD) 到28.1% (查),与一般人口患病率相比显著丰富.
UKB验证显示,共有变异的参与者中有16.1%-27.9%具有IRD特征.
人口统计,生活方式和并发症并不能预测透性.
IRD基因型的人口透率明显低于假设,实际的基因型流行率为0.7%-2.1%.

结论:

与IRD相关的基因型比以前认为的更为普遍.
透率低于预期,表明疾病发展需要基因或环境修饰剂.
这些发现需要对基因测试策略进行重新评估,并为IRDs开发治疗方法.

The Retinoblastoma Gene

The Retinoblastoma Gene

Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...

Photoreceptors and Visual Pathways

Photoreceptors and Visual Pathways

At the molecular level, visual signals trigger transformations in photopigment molecules, resulting in changes in the photoreceptor cell's membrane potential. The photon's energy level is denoted by its wavelength, with each specific wavelength of visible light associated with a distinct color. The spectral range of visible light, classified as electromagnetic radiation, spans from 380 to 720 nm. Electromagnetic radiation wavelengths exceeding 720 nm fall under the infrared category,...

Incomplete Dominance

Incomplete Dominance

Gregor Mendel's work (1822 - 1884) was primarily focused on pea plants. Through his initial experiments, he determined that every gene in a diploid cell has two variants called alleles inherited from each parent. He suggested that amongst these two alleles, one allele is dominant in character and the other recessive. The combination of alleles determines the phenotype of a gene in an organism.
