Overcome the Limitation of Phenome-Wide Association Studies (PheWAS): Extension of PheWAS to Efficient and Robust Large-Scale ICD Codes Analysis

ABSTRACT The Phenome-wide association studies (PheWAS) have become widely used for efficient, high-throughput evaluation of relationship between a genetic factor and a large number of disease phenotypes, typically extracted from a DNA biobank linked with electronic medical records (EMR).

Assessment of Avifaunal Diversity and Threats to them in Phewa Wetland, Nepal

Forestry: Journal of Institute of Forestry, Nepal, 2019
We assessed species diversity and relative abundance during February - March by employing transect method in four line transects and 30 point count stations, and associated threats by direct observations and consultation with people (n= 1) living in vicinity of Phewa wetland. We counted 2651 bird individuals of 148 species belonging to 104 Genera of 44

Identifying potential causal effects of Parkinson’s disease: A polygenic risk score-based phenome-wide association and mendelian randomization study in UK Biobank

npj Parkinson's Disease
There is considerable uncertainty regarding the associations between various risk factors and Parkinson’s Disease (PD). This study systematically screened and validated a wide range of potential PD risk factors from 502,364 participants in the UK Biobank.

Exploring various polygenic risk scores for skin cancer in the phenomes of the Michigan genomics initiative and the UK Biobank with a visual catalog: PRSWeb.

PLoS Genetics, 2019
Polygenic risk scores (PRS) are designed to serve as single summary measures that are easy to construct, condensing information from a large number of genetic variants associated with a disease.

11 Novel Systematic Method for Identifying Congenital Anomaly Cases in Electronic Health Record Databases

Journal of Clinical and Translational Science
OBJECTIVES/GOALS: Congenital anomalies (CAs) affect 3% of live births, yet the cause of 80% of CAs is unknown and for the 20% with an identified cause, variability in penetrance suggests additional risk drivers exist.

Heterogeneous associations between interleukin-6 receptor variants and phenotypes across ancestries and implications for therapy

Scientific Reports
The Phenome-Wide Association Study (PheWAS) is increasingly used to broadly screen for potential treatment effects, e.g., IL6R variant as a proxy for IL6R antagonists. This approach offers an opportunity to address the limited power in clinical trials to

Exploring Effects of Age at the Onset of Myopia on Multiple Diseases Using Electronic Health Records

Ophthalmology Science
Purpose: To examine whether genetic predisposition to age at the onset of myopia is associated with the development of future diseases. Design: Mendelian randomization phenome-wide association study (MR-PheWAS) from the UK Biobank.
