项目摘要
Abstract
The goal of this proposal is to establish a novel artificial intelligence-based strategy of genome
wide association studies (GWAS) to identify new genetic loci associated with common human
disorders. Identification of the genetic factors underlying these diseases will provide not only
mechanistic insights into the diseases but also form the basis for developing novel preventative,
diagnostic, and targeted therapeutic methods. While GWAS has achieved great successes in
the past 1.5 decades, only a small portion of common diseases' heritability can be currently
explained by loci identified from traditional GWAS. Leveraging on the public genetics and
clinical imaging data, we propose a novel approach, termed image based GWAS (iGWAS),
where GWAS will be performed on endophenotypes derived from images using cutting edge
deep learning (DL) algorithms. By creating a more objective and quantitative output from the
images, with less information loss, many new disease-associated genetic loci are expected to
be identified. To test the efficacy of this novel approach, the human visual system will be used
as an example. A DL-phenotyper, Multi-modal multi-view Self-Supervised deep Learning
Encoder for Retinal images (MuSSLER), will be developed to extract quantitative output from
optical coherence tomography scans and fundus images from both normal eyes and patients
with diabetic retinopathy (DR). GWAS will be performed on normal eye endophenotypes to
elucidate genes relevant to retina development and physiology. Also, GWAS will be performed
on DR-specific endophenotypes to identify DR associated genetic loci and candidate genes. If
successful, our approach represents a general framework that can be readily extended to the
study of other retinal diseases and other common diseases with imaging data. Furthermore, the
phenotyping neural network architecture established in this project can be readily adopted to
develop an automated grading tool for heterogeneous clinical data and applied to many other
common diseases.
抽象的
该提案的目标是建立一种新颖的基于人工智能的基因组策略
广泛关联研究(GWAS),以确定与普通人类相关的新遗传位点
失调。识别这些疾病背后的遗传因素不仅可以提供
对疾病的机制见解,也构成开发新型预防措施的基础,
诊断方法和靶向治疗方法。虽然 GWAS 在以下方面取得了巨大成功
过去1.5年,目前只有一小部分常见疾病的遗传力
通过传统 GWAS 确定的基因座进行解释。利用公共遗传学和
临床影像数据,我们提出了一种新方法,称为基于图像的 GWAS (iGWAS),
将使用尖端技术对源自图像的内表型进行 GWAS
深度学习 (DL) 算法。通过创建更加客观和定量的输出
图像,信息丢失较少,许多新的与疾病相关的遗传位点有望
被识别。为了测试这种新颖方法的功效,将使用人类视觉系统
举个例子。 DL-表型,多模态多视图自监督深度学习
视网膜图像编码器(MuSSLER)将被开发来提取定量输出
正常眼睛和患者的光学相干断层扫描和眼底图像
患有糖尿病视网膜病变(DR)。将对正常眼睛内表型进行 GWAS,以
阐明与视网膜发育和生理学相关的基因。此外,还将进行 GWAS
DR 特异性内表型,以确定 DR 相关基因位点和候选基因。如果
成功后,我们的方法代表了一个可以轻松扩展到的总体框架
利用影像数据研究其他视网膜疾病和其他常见疾病。此外,
该项目中建立的表型神经网络架构可以很容易地采用
开发针对异构临床数据的自动分级工具并应用于许多其他
常见疾病。
