IgA N-glycans associations at the ST6GAL1, MGAT3, and ELL2 loci were also identified in QMDiab (Table 1 and Additional file 1: Table S15), with lead SNPs at the ST6GAL1 and ELL2 loci being coincident or in strong linkage disequilibrium (LD) with previously reported associations for IgA nephropathy and multiple myeloma risk, respectively (Table 1). The gene discussed is CD79A; the disease is AL amyloidosis.
