Significantly higher titre of anti-LGALS3 antibody was detected in sera from T1AD patients (versus T2D patients; P = 0.0010, versus AITD patients; P = 0.0134, versus HC; P = 0.0006), but not in sera from FT1D patients in either the acute or sub-acute phase (Fig 4). The gene discussed is LGALS3; the disease is type 2 diabetes mellitus.
