In addition to GLK 3′-UTR, three (all females) of 101 Cohort #1 patients with SLE showed a GLK germline variant at the codon p.Ala410 to Thr (GCA to ACA) with 1.163% allele frequency (figure 1A and table 2); this variant is a previously annotated SNP, rs148167737. Here, MAP4K3 is linked to systemic lupus erythematosus.
