Evaluating practical approaches for including MYOC variants alongside common variants for genetics-based risk stratification for glaucoma: Including MYOC Variants for Glaucoma Risk Stratification
The researchers investigated methods for identifying carriers of the p.Gln368Ter variant in the MYOC gene, associated with glaucoma risk, using data from the Genetics of Glaucoma (GOG), the QSkin Sun and Health Study (QSKIN), and CARTaGENE cohorts. They found that direct genotyping, with proper quality control measures, showed high accuracy and perfect concordance with sequencing data. Incorporating p.Gln368Ter status into polygenic risk scores (PRS) significantly improved risk stratification for carriers, increasing the proportion classified as high-risk in QSKIN and CARTaGENE. However, adding this variant to PRS did not enhance overall risk prediction for the general population.
150 risk variants for diverticular disease of intestine prioritize cell types and enable polygenic prediction of disease susceptibility
This study includes data from over 724,000 individuals, including data from 7,696 CARTaGENE participants. Researchers identified 150 genetic variants associated with diverticular disease (DivD) of the intestine. Their findings suggest that DivD may be linked to factors related to colon structure, gut motility, gastrointestinal mucus, and ionic balance. Notably, one of the identified genes is a target for a drug used to treat irritable bowel syndrome (IBS), highlighting a potential connection between these two gastrointestinal conditions.
Global Biobank Meta-analysis Initiative: Powering genetic discovery across human disease
The Global Biobank Meta-analysis Initiative is a collaborative network of 23 biobanks, representing more than 2.2M consented participants with genetic data linked to electronic health records. This collaborative effort will improve genome-wide association studies’ power for diseases, benefit understudied diseases, and improve risk prediction.
