Diseases - Mr Validity (2025)

: When a gene affects multiple traits independently, potentially biasing the causal estimate.

: Used to study the causal impact of alcohol, smoking, blood pressure, and cholesterol on various chronic diseases . ⚠️ Challenges to Validity

For an MR report to be considered valid, it must demonstrate that the genetic instruments (SNPs) meet these criteria: Diseases - Mr Validity

: The genetic variants must be strongly associated with the exposure of interest.

: Differences in ancestry within a study can create false associations. 🛠️ Related Tools & Models : When a gene affects multiple traits independently,

: The genetic variants affect the outcome only through the exposure, with no alternative biological pathways (a phenomenon known as horizontal pleiotropy). 📊 Key Components of an MR Study

: Uses summary statistics from two separate groups (e.g., one group for LDL levels and another for heart disease data), which is often more cost-effective.
