The files below list the variants for

  • breast cancer PRS: BCAC 77; BCAC 313; BCAC 3820BRIDGES 306; EGLH-CEN 303; PERSPECTIVE 295PRISMA 268; WISDOM 75; WISDOM 128.

  • ovarian cancer PRS: OCAC 36OC-EGLH-CEN 34.

In the header in each file is the square root of the proportion of the overall polygenic variance explained by the PRS (alpha). The rest of the file consists of data records containing the following comma separated fields:

  • name - the name of the variant

  • chromosome - the chromosome on which the variant resides

  • position -  Build 37 (hg19), with 1-based variant positions

  • reference_allele - the reference allele for the variant

  • effect_allele - the effect allele for the variant

  • log_odds_ratio - the log odds ratio for the variant

  • effect_allele_frequency - the allele frequency for the variant

Note: For use in BOADICEA, once the vcf file is uploaded, a raw PRS is calculated and standardised using the following mean and standard deviation parameters. These calculations are done internally.
