Enrichment:
- report enrichment regression coefficient
  * regressing empirical GxE scores on putative GxE rankings or variant functions.
- 3 tables
  * internal: UKBB British Whites on non-British Whites
  * external: UKBB Whites on PEGS participants.
  * functional: UKBB Whites on ANNOVAR labels and CPDD scores.

PEGS joined with VLA:
- Results of 2-way GxE-WAS on PEGS, joined with putative GxE statistics based on UKBB.
- limited to significant results:
  * GxE p-values <= 1e-4
  * Bonferroni correctd and later adjusted p-values < 0.05
- used two phenotypes
  * BMI and T2D

UKBB Top Hits:
- most significant putative GxE test statistics from UKBB
- for two phenotypes:
  * t2d and bmi
