Nonetheless, for t -test significant SNPs P emp not passing the Shapiro–Wilk test, we verified the result by checking for a nominally significant Mann–Whitney U test at p < 0.05.

For SNPs with significant allele and interaction coefficients, a meaningful allele main effect was considered present if the single-condition vehicle and ATRA analyses showed the same allelic direction of effect, with a vehicle Pemp < 0.1 and ATRA FDR < 0.1 (i.e., near-significant within each condition of n = 6, thus reasonably capable of achieving significance in the LMM analysis of the two conditions combined).
