TSC2 and viral infectious disease: The flanking regions of the three SNPs with the lowest p‐values in all GWAS contained four genes with known relevance in viral infection pathways: S‐adenosyl homocysteinase (SAHH, SNP p = 2.88 × 10−21), E3 ubiquitin‐protein ligase Itchy (ITCH, SNP p = 7.66 × 10−20) and the two genes Synaptogyrin‐3 and Tuberous Sclerosis Complex 2 near the third locus (Syngr03/TSC2, SNP p = 1.8 × 10−17; Table 2).
