ECG Plotter

Enter a list of SNPs (rs572474770, rs776293589, 2:179698596), a region (2:179381323-179405807) or a Gene (e.g. SCN5A) and click the Go button to extract variants.

(note: Microsoft browsers may not work, try disabling bitdefender)

Colors indicate LD (r2); filled circles indicate the significance of the lead ECG trait; hollow circles indicate the minimum value across ECG all traits.


Please limit to <150 for now, else it will probably fail to plot due to memory issues.

Interactive t-SNE plot (manuscript)

ECG-wide Mendelian randomization

Provide a summary statistics file with up to 1000 variants. Include the following columns with headers: CHR, BP, EFAL, NEFAL, EAF, BETA, SE. Ensure positions are on Build 37. This is a try-out. It may be very slow since it needs to query the full 75 GB gz-compressed data and the VPS has no superpowers. Download an example (QT interval) here.
