Predicted Trait
Reported Trait Insomnia
Mapped Trait(s) insomnia (MONDO_0013600)
Additional Trait Information Insomnia GWAS summary statistics from UK Biobank and MVP European-ancestry participants were meta-analyzed before score construction. UKB used a self-reported insomnia-symptom question; MVP used qualifying ICD-9/10 diagnosis codes.

Score Details

Score Construction
PGS Name Insomnia UKB+MVP EUR (meta-analyzed)
Development Method
Name PRS-CS
Parameters UKB and MVP EUR GWAS summary statistics were meta-analyzed using GWAMA v2.2.2 with default settings. Posterior SNP effect sizes were then inferred using PRS-CS with the 1000 Genomes European LD reference panel, HapMap target variants, a=1, b=0.5, phi=auto, and other parameters default; no clumping or P-value thresholding.

Performance Metrics

Disclaimer: The performance metrics are displayed as reported by the source studies. It is important to note that metrics are not necessarily comparable with each other. For example, metrics depend on the sample characteristics (described by the PGS Catalog Sample Set [PSS] ID), phenotyping, and statistical modelling. Please refer to the source publication for additional guidance on performance.

 Reported Trait: Insomnia (WHIIRS >=10, or modified 3-question WHIIRS >=6 in ARIC) OR: 1.27 — — Age, sex, study center, ancestry principal components; race additionally included in BHS. The score was constructed from meta-analysed UKB and MVP European-ancestry GWAS summary statistics using PRS-CS and evaluated across ARIC, HCHS/SOL, MESA and BHS. Significant between-study heterogeneity was observed (p for heterogeneity = 0.006); the manuscript also reports random-effects results. HCHS/SOL analyses incorporated sampling weights.
